If you have ever finished a hike with uncomfortable chafing or bunching, you already know that the wrong underwear can turn a beautiful day outdoors into a miserable experience. The truth is, regular cotton underwear is not built for hiking – it traps moisture, creates friction, and leaves you uncomfortable within the first mile. But here is the good news: choosing the right hiking underwear is one of the simplest upgrades you can make to your outdoor comfort, and you do not need to spend a fortune or become a gear expert to get it right.
This guide will walk you through the best hiking underwear for men, specifically chosen for beginners who want to solve the chafing problem and focus on enjoying the trail. We have tested and researched options across different price points and styles, so you can find the pair that works for your body, your budget, and the kind of hiking you are doing. Whether this is your first pair of performance underwear or you are replacing something that did not work, you will find a clear recommendation here.
What to Look For
Fabric Matters More Than You Think
The single most important decision you will make when choosing hiking underwear is the fabric. Cotton feels soft at home, but on the trail it absorbs sweat and stays wet, which creates friction and leads to chafing. Performance fabrics are designed to wick moisture away from your skin and dry quickly, keeping you comfortable even when you are sweating. The three most common options are synthetic blends (usually polyester or nylon), merino wool, and bamboo-derived viscose. Synthetic fabrics are the most affordable and dry the fastest, making them a great choice for hot weather or high-intensity hikes. Merino wool is naturally odor-resistant and temperature-regulating, which means it works well in both warm and cool conditions – though it costs more and takes longer to dry. Bamboo-derived fabrics offer a middle ground with softness and moisture control at a reasonable price. For most beginners, a synthetic or bamboo blend offers the best balance of comfort, performance, and value.
Fit and Style: Boxer Briefs Are Your Best Bet
When it comes to hiking, fit is everything. Loose boxers can bunch up under your hiking pants and cause irritation, while tight compression shorts can feel restrictive if you are not used to them. Boxer briefs are the goldilocks option for most hikers – they provide enough coverage to prevent thigh chafing, stay in place during movement, and offer support without feeling constricting. Look for a pair with a longer inseam (around 6 to 9 inches) if you are prone to chafing between your thighs, or a shorter inseam (around 3 to 5 inches) if you prefer less fabric. Pay attention to the waistband, too. A soft, flexible waistband will not dig into your skin when you are wearing a hip belt on your backpack. Some underwear also features a fly, which is a personal preference – it adds convenience but is not essential for hiking performance.
Moisture-Wicking and Quick-Drying Features
Moisture-wicking means the fabric pulls sweat away from your skin and spreads it across the surface of the material so it can evaporate quickly. This is not just about comfort – keeping your skin dry prevents the friction that causes chafing and reduces the risk of irritation on longer hikes. Quick-drying fabric is especially important if you are planning multi-day trips or hiking in humid conditions, because it allows you to wash your underwear at camp and have it dry by morning. Look for product descriptions that mention moisture-wicking, quick-dry, or breathable mesh panels. These features are standard in most performance underwear, but not all products are created equal. Cheaper options may claim to wick moisture but use heavier fabrics that take longer to dry. Reading customer reviews can help you identify which products actually deliver on these promises in real-world hiking conditions.
Anti-Chafe Construction and Flatlock Seams
Chafing happens when fabric rubs against your skin repeatedly, and seams are often the worst offenders. Flatlock seams lie flat against the fabric instead of creating a raised ridge, which dramatically reduces irritation. Many hiking underwear brands also eliminate seams in high-friction areas entirely or use tagless construction to avoid irritation at the waistband. Some products include additional features like a contoured pouch or anatomical design, which provide support and reduce movement that can lead to chafing. If you have experienced chafing on previous hikes, prioritize underwear that specifically mentions anti-chafe construction or flatlock seams in the product description. These small design details make a big difference over miles on the trail, especially if you are carrying a backpack or hiking in warm weather.
Odor Control for Multi-Day Comfort
If you are planning day hikes, odor control is a nice-to-have feature. But if you are considering overnight trips or multi-day hikes, it becomes much more important. Merino wool is naturally antimicrobial, which means it resists odor-causing bacteria even after multiple wears. Some synthetic underwear is treated with antimicrobial finishes to achieve a similar effect, though these treatments can fade over time with repeated washing. Bamboo-derived fabrics also offer natural odor resistance. For beginners who are still figuring out whether they will pursue overnight hiking, starting with a synthetic or bamboo option is perfectly fine – you can always upgrade to merino wool later if you find yourself hiking more frequently. Just avoid cotton, which retains odor as well as moisture and will become uncomfortable quickly on longer trips.
Price and Value: How Much Should You Spend
Hiking underwear ranges from around 15 dollars per pair for budget-friendly multipacks to 50 dollars or more for premium merino wool options. As a beginner, you do not need to start at the high end. A quality synthetic or bamboo boxer brief in the 20 to 30 dollar range will solve the chafing problem and perform well on most day hikes. If you find yourself hiking regularly and want to invest in gear that will last longer or perform better on multi-day trips, merino wool is worth the upgrade. Multipacks are a smart choice because they allow you to rotate pairs between hikes and extend the life of each one. Look for products with high review counts and consistent ratings above 4.5 stars – this indicates that other hikers have tested the product in real conditions and found it reliable. Avoid the temptation to stick with your regular cotton underwear just to save money – the discomfort is not worth it, and even a budget-friendly performance pair will make a noticeable difference on your first hike.
Our Top Picks
1. BAMBOO COOL Men’s Underwear Boxer Briefs Fly with Built-in 3D Pouch Comfortable Cool Underwear for Men 4 Pack
Best overall for beginners seeking comfort and value in their first performance underwear
This BAMBOO COOL boxer brief offers exactly what most beginner hikers need: reliable moisture-wicking performance at a price that does not require a big commitment. The 4-pack format means you can rotate pairs between hikes without doing laundry constantly, and at around 7 dollars per pair, this is one of the most affordable entries into performance underwear. The bamboo-derived fabric feels noticeably softer than cheaper synthetic options while still delivering quick-drying performance when you are sweating on the trail. The anatomical design provides comfort without feeling restrictive, and the functional fly adds convenience for bathroom breaks on longer hikes.
What makes this option particularly beginner-friendly is the balance it strikes between performance and everyday comfort. You can wear these on a hike and then around camp or even as regular underwear, which means you are more likely to actually use them instead of leaving them in a drawer. The fabric is breathable enough to prevent overheating on warm-weather hikes but substantial enough that it does not feel flimsy or see-through. Customer reviews consistently mention the comfort and fit, with over 5,700 ratings averaging 4.6 stars – a strong indicator that this product delivers for real users across different body types and hiking conditions.
The main limitation is that these are not designed for extreme conditions or multi-day backpacking trips where odor control becomes critical. The bamboo fabric offers some natural odor resistance but not at the level of merino wool. If you are planning mostly day hikes or weekend trips where you will have access to laundry, this is not an issue. The waistband is flexible and comfortable under a backpack hip belt, and the construction quality is solid enough to avoid irritation on hikes up to 10 miles or more. For someone taking their first steps into hiking-specific gear, this pack delivers real performance improvements over cotton without the premium price tag of specialty outdoor brands.
Pros
- Excellent value with 4-pack format at affordable price point
- Soft bamboo-derived fabric that wicks moisture effectively
- Functional fly and comfortable anatomical design
- Over 5,700 customer reviews with consistent 4.6-star rating
Cons
- Odor resistance is good but not as strong as merino wool options
- Not ideal for multi-day backpacking without washing access
2. Under Armour Tech 9″ Boxerjock 2-Pack
Best for hikers who need longer inseam to prevent thigh chafing on demanding trails
The 9-inch inseam on this Under Armour Boxerjock makes it the best option for hikers who struggle with thigh chafing, especially on longer or more strenuous hikes. That extra length provides coverage where your thighs rub together during movement, which is exactly where chafing becomes most painful after several miles on the trail. The synthetic fabric is engineered for athletic performance and wicks moisture quickly, while the construction enhances airflow in areas that tend to trap heat. Under Armour has been making performance athletic wear for years, and that experience shows in the construction quality and durability of these boxer briefs.
What sets this product apart is the combination of coverage and performance features at a reasonable price. At around 12.60 dollars per pair in this 2-pack, you are paying a bit more than budget multipacks, but you are getting a product from a brand with a proven track record in athletic performance. The longer inseam stays in place during movement without riding up, which is a common complaint with shorter styles. The fabric moves with your body whether you are scrambling over rocks or taking long strides on flat trails, and the anti-odor technology helps keep things fresh even after a full day of hiking in warm weather.
The main consideration with this style is that the longer inseam may feel like too much fabric if you are used to shorter underwear or are hiking in very hot conditions. Some users also mention that the waistband is slightly firmer than softer bamboo or merino options, though it does not dig in or cause discomfort under a backpack hip belt. With over 8,400 reviews and a 4.7-star rating, this is clearly working well for a large number of active users. If you have dealt with painful chafing on past hikes and want a solution that provides maximum coverage, the longer inseam on this Boxerjock is worth the slightly higher price per pair.
Pros
- 9-inch inseam provides excellent coverage to prevent thigh chafing
- Quick-drying synthetic fabric engineered for athletic performance
- Anti-odor technology for all-day freshness
- Over 8,400 reviews with 4.7-star rating from active users
Cons
- Longer inseam may feel like too much fabric in very hot weather
- Waistband is slightly firmer than softer fabric options
3. Hanes Men’s Total Support Pouch Men’s Boxer Brief Underwear, Anti-chafing, Moisture-wicking Odor Control, 3-pack
Best budget option for beginners who want reliable anti-chafe performance without premium pricing
With nearly 44,000 customer reviews and a 4.6-star rating, this Hanes Total Support Pouch boxer brief is the most extensively tested product on this list – and it delivers exactly what budget-conscious beginners need. At just under 7 dollars per pair in this 3-pack, it is one of the most affordable ways to solve the chafing problem without sacrificing real performance. The anti-chafing construction and moisture-wicking fabric handle the basics well, keeping you dry and comfortable on day hikes up to moderate distances. The design provides structure without feeling overly constrictive, and the odor control feature works well enough for single-day use.
What makes this option particularly appealing for beginners is the low financial barrier to entry. If you are not sure whether performance underwear will make a difference for you, spending around 21 dollars on a 3-pack is a low-risk way to find out. The Hanes brand is widely available and familiar, which means you know what you are getting in terms of quality and construction. These boxer briefs work well for weekend warriors who hike occasionally and need something better than cotton but are not ready to invest in premium outdoor brands. The fabric is not as soft as bamboo or merino wool options, but it is durable and holds up to repeated washing without losing its shape or performance.
The main limitation is that this is a budget product, and it shows in the details. The fabric is thinner than more expensive options, which some users find less comfortable during extended wear. The moisture-wicking performance is adequate for moderate activity but may not keep up on very hot days or high-intensity hikes where you are sweating heavily. The odor control is functional for day hikes but not robust enough for overnight trips without washing. For someone just getting started with hiking and testing out different gear, this Hanes pack offers proven performance at a price point that makes sense. Once you know you love hiking and want to upgrade, you can invest in something more advanced – but this will serve you well in the meantime.
Pros
- Exceptional value at approximately 7 dollars per pair
- Massive 43,923 customer reviews with 4.6-star rating prove reliability
- Anti-chafing construction and moisture-wicking fabric handle day hikes well
- Widely available Hanes brand with consistent quality
Cons
- Thinner fabric compared to premium options
- Moisture-wicking performance is adequate but not exceptional for intense activity
- Odor control is functional for day use but limited for overnight trips

4. ExOfficio Men’s Give-N-Go 2.0 Boxer Brief 2 Pack
Best premium choice for multi-day hiking and travel with exceptional durability
The ExOfficio Give-N-Go 2.0 is the product that serious hikers mention first when discussing underwear, and for good reason. At 27.50 dollars per pair in this 2-pack, it is definitely a premium investment – but the performance and durability justify the price if you are planning multi-day hikes or want underwear that will last for years. The synthetic fabric is engineered specifically for travel and outdoor use, with exceptional quick-drying performance that allows you to wash a pair in a stream or sink and have it dry overnight. The antimicrobial treatment provides genuine odor control even after multiple wears, which is critical when you are carrying limited clothing on a backpacking trip.
What separates this from cheaper options is the attention to detail in the construction. The fabric is thicker and more substantial than budget synthetics without feeling heavy or restrictive. The seams are designed to minimize irritation points, and the ventilation zones maximize airflow in high-sweat areas. The fit is refined through years of feedback from travelers and hikers, which shows in how well these stay in place during movement without any adjustment needed. ExOfficio has built a reputation specifically in the outdoor and travel community, and this product delivers on that reputation consistently across different body types and use cases.
The main consideration is the price – you are paying more than double what budget options cost, and for beginners who are still figuring out whether hiking will become a regular activity, that may not make sense yet. These are also designed with travel and multi-day use in mind, so if you are only planning occasional day hikes, you may not need the advanced features this product offers. However, if you know you want to pursue overnight hiking or multi-day trips, investing in a quality pair from the start saves you from buying multiple cheaper options that do not perform as well. The 1,639 reviews with a 4.6-star rating indicate that users who invest in this product are consistently satisfied with the performance and longevity.
Pros
- Exceptional quick-drying performance for multi-day trips and travel
- Genuine antimicrobial odor control after multiple wears
- Premium construction with careful attention to comfort details
- Proven durability and reputation in the hiking and travel community
Cons
- Premium price at 27.50 dollars per pair may not make sense for occasional day hikers
- Features are designed for multi-day use that beginners may not need yet

5. New Balance Men’s Performance Boxer Briefs with Fly, Breathable Stretch Underwear, Moisture Wicking, Soft Waistband (3 Pack)
Best for beginners who prioritize a soft waistband that will not irritate under a backpack hip belt
With over 85,000 customer reviews, this New Balance boxer brief is the most extensively validated product in the budget-to-midrange category – and that massive review count tells you something important about its reliability. At around 6.66 dollars per pair in this 3-pack, it offers performance features that punch well above its price point. The soft waistband is specifically worth noting for hikers, because it provides comfort under a backpack hip belt without the digging or rolling that firmer waistbands can cause after several hours on the trail. The stretch fabric moves with your body and wicks moisture effectively for day hikes in varied conditions.
What makes this New Balance option stand out is the combination of athletic brand quality and hiking-appropriate features at an accessible price. The functional fly adds convenience, and the moisture-wicking performance keeps you dry during moderate to high activity levels. The fabric is soft enough for all-day comfort but durable enough to hold up to repeated washing and wear. New Balance has experience making performance athletic wear, and that expertise shows in the construction and fit. These boxer briefs work well for beginners who want something better than cotton but are not ready to commit to premium outdoor-specific brands.
The main limitation is that the fabric is slightly thicker than ultra-lightweight options, which some users find less ideal in very hot weather. The odor control is adequate for day hikes but not as robust as treated synthetic or merino wool options for overnight use. However, for the vast majority of beginner hikers who are doing day trips or weekend outings with laundry access, these perform exceptionally well. The 85,324 reviews with a 4.6-star average indicate that this product consistently delivers across a wide range of users and use cases. If you want a soft, comfortable option from a trusted athletic brand at a budget-friendly price, this New Balance 3-pack is an excellent starting point.

- Stretch fabric with effective moisture-wicking for day hikes

How These Compare
Choosing between these five options comes down to your hiking plans and budget. If you are just getting started and want to test whether performance underwear makes a difference without spending much, the Hanes Total Support Pouch at around 7 dollars per pair offers proven anti-chafe performance with nearly 44,000 reviews backing it up. It handles day hikes well and gives you a reliable baseline to understand what performance underwear can do.

The extra coverage prevents that painful rubbing between your thighs that can ruin a hike, and the fabric stays in place without riding up.

For those planning multi-day trips or who want to invest in gear that will last for years, the ExOfficio Give-N-Go 2.0 is worth the premium price. The quick-drying performance and genuine antimicrobial odor control make it ideal for backpacking trips where you cannot wash clothes daily, and the durability means you will not need to replace them after a season of use. Yes, you are paying 27.50 dollars per pair, but you are getting a product that performs at a higher level and lasts significantly longer than cheaper alternatives. If you are still figuring out whether hiking will become a regular activity, start with one of the budget options and upgrade to ExOfficio once you know this is a hobby you will pursue seriously.
Frequently Asked Questions
Should I wear underwear while hiking?
Yes, wearing the right underwear while hiking significantly improves your comfort and helps prevent chafing. The key is choosing performance underwear made from moisture-wicking fabrics instead of regular cotton. Cotton absorbs sweat and stays wet against your skin, which creates friction and leads to painful chafing after a few miles on the trail. Performance underwear made from synthetic materials, merino wool, or bamboo-derived fabrics pulls moisture away from your skin and dries quickly, keeping you comfortable throughout your hike. Some hikers choose to go commando (without underwear) to reduce friction points, but this only works if you are wearing high-quality hiking pants with a built-in liner or soft fabric that will not irritate your skin. For most beginners, wearing proper hiking underwear is the simpler and more comfortable option. The right pair of boxer briefs provides support, prevents chafing between your thighs, and eliminates the discomfort that can turn a beautiful hike into a painful experience. If you have been hiking in regular cotton underwear and experiencing discomfort, switching to performance underwear is one of the easiest and most effective gear upgrades you can make.
What is the best material for hiking underwear?
The best materials for hiking underwear are synthetic fabrics like polyester or nylon, merino wool, and bamboo-derived viscose – all of which wick moisture and dry quickly. Synthetic fabrics are the most affordable and offer the fastest drying times, making them ideal for hot weather or high-intensity hikes where you are sweating heavily. They are lightweight, durable, and easy to care for, though some cheaper synthetics can retain odor after extended use. Merino wool is naturally antimicrobial and odor-resistant, which makes it excellent for multi-day trips where you cannot wash clothes regularly. It also regulates temperature well, keeping you cool in warm weather and warm in cool conditions. The main drawbacks are higher cost and slower drying times compared to synthetics. Bamboo-derived fabrics offer a middle ground with exceptional softness, good moisture-wicking, and natural odor resistance at a more affordable price than merino wool. The one material to absolutely avoid is cotton, which absorbs moisture and stays wet against your skin, creating the friction that causes chafing. For beginners doing day hikes, synthetic or bamboo options provide the best combination of performance and value. If you plan to pursue multi-day backpacking trips, merino wool is worth the investment for its superior odor control.
How do I prevent chafing while hiking?
Preventing chafing while hiking starts with wearing moisture-wicking underwear that keeps your skin dry and reduces friction. Choose boxer briefs with a longer inseam if you experience thigh chafing, as the extra coverage prevents skin-on-skin rubbing that causes irritation. Look for underwear with flatlock seams or seamless construction in high-friction areas, since raised seams can dig into your skin during repetitive movement. Apply anti-chafe balm or petroleum jelly to problem areas before your hike – common spots include inner thighs, underarms, and anywhere your backpack straps or hip belt make contact with your body. Stay hydrated during your hike, as dehydration can make your skin more prone to irritation. If you start to feel hot spots or discomfort developing, address it immediately rather than pushing through – apply more balm, adjust your clothing, or take a short break to let your skin cool down. Wearing proper hiking pants that fit well and do not bunch up also reduces chafing, since loose fabric creates additional friction points. After your hike, shower as soon as possible and apply a soothing lotion to any areas that feel irritated. With the right underwear and these preventive steps, you can avoid the painful chafing that has ruined hikes in the past and focus on enjoying your time outdoors.
Can you wear compression shorts for hiking?
Yes, you can wear compression shorts for hiking, and they work well for some people – but they are not necessary for most beginner hikers. Compression shorts are designed to provide muscle support and reduce fatigue during high-intensity activity, which can be beneficial on challenging hikes with significant elevation gain or long distances. The tight fit also eliminates fabric bunching and provides maximum coverage to prevent thigh chafing. However, the snug compression fit can feel restrictive if you are not used to it, and some hikers find them uncomfortable for casual or moderate hikes where muscle support is not needed. Compression shorts also tend to cost more than regular performance boxer briefs. For most beginners doing day hikes on moderate trails, standard moisture-wicking boxer briefs provide all the performance you need without the tight compression feel. If you already own compression shorts from other athletic activities, they will certainly work for hiking – just make sure they are made from moisture-wicking fabric and not cotton. If you are buying underwear specifically for hiking, start with boxer briefs, which offer a better balance of comfort, coverage, and performance for general trail use. You can always experiment with compression shorts later if you find yourself doing more challenging hikes where the added support would be beneficial.
The Bottom Line
Finding the right hiking underwear does not have to be complicated, but it does make a real difference in your comfort on the trail. If you are dealing with chafing or discomfort on your current hikes, any of these five options will solve that problem better than regular cotton underwear. For most beginners, the BAMBOO COOL 4-pack offers the best overall value – you get soft, moisture-wicking fabric and enough pairs to rotate between hikes without breaking the budget. If thigh chafing has been a specific issue for you, choose the Under Armour Tech 9-inch Boxerjock for its longer inseam and proven anti-chafe performance. Budget-conscious hikers who want to test performance underwear without much financial commitment will find the Hanes Total Support Pouch delivers reliable results at the lowest price point.
If you are planning to pursue multi-day hiking or backpacking trips, invest in the ExOfficio Give-N-Go 2.0 from the start – the quick-drying performance and genuine odor control are worth the premium price when you cannot wash clothes daily. And if comfort under a backpack hip belt is your main concern, the New Balance option with its soft waistband provides all-day comfort at an accessible price. Whichever option you choose, you will immediately notice the difference from cotton underwear on your very first hike. Your skin will stay drier, you will avoid painful chafing, and you can focus on enjoying the trail instead of adjusting uncomfortable clothing. Start with one or two pairs to test the fit and performance, then add more once you know which style works best for your body and hiking plans.
