Buyer’s Guide

When on an outdoor expedition, your comfort is paramount. A bad choice of underwear can curtail your hiking experience. A low-quality undie can chaff your skin, retain moisture, provides less support, can get loose and slip, and can even get smelly and itchy. So, to avoid such things from happening, let’s discuss some vital factors that you should consider while choosing the best hiking underwear for men.


Material that is commonly used to manufacture the usual city clothes is cotton. But, cotton is not a good choice when you are indulged in some active work or during a cold or wet environment. Cotton have the tendency to absorb water and after that, it gets heavy, dries slowly, and does not insulate. Hence, when hiking, you are likely to get sweaty, and cotton is not a material that you will want to feel against your skin. So, we won’t recommend you to go for cotton fabric.

Mainly we have got two material choices for hiking underwear, i.e., merino wool (natural fiber) and synthetic fibers (primarily polyester or nylon).

Both of these materials have their pros and cons. Both of these have got amazing moisture-wicking features. Additionally, they dry up quickly and are good at keeping you insulated when wet.

The positive thing about merino wool is that it is really soft and is naturally odor-resistant too. It even feels comforting against the skin when wet. But, there are some downsides too. Merino is a bit more expensive than other synthetic materials and is quite less durable too.

The downsides of merino become the upsides of synthetic material. They are less expensive and more durable. But, they are not as soft as merino and doesn’t feel too nice when damp.

So, the choice of material will depend on your demand for durability, budget, comfort and other preferences.

These days, manufacturers are making use of a blend of both materials. The combination results in the wrapping of merino wool over the synthetic nylon core. It offers you the best of both worlds, merino provides softness and comfort, and synthetic fabric adds durability.


You will find two types of cut, in general, when you look for hiking underwear. Manufacturers usually offer you boxers or boxer briefs.

Boxers are more of a loose cut underwear similar to shorts. On the other hand, briefs offer you a more snug fit than boxers. They provide a better fit at the thigh area.

The cuts usually vary from manufacturer to manufacturer. So, simply a label cannot tell you the full story. You need to take a good look at the cuts offered by each manufacturer and then make an informed choice.

In general, for active work, people prefer to use a more athletic underwear with tight-fitting. But, you should remember, a too-tight fit can make you sweat more and lack of washing can result in chafing. So, a brief is fine but avoid too much tightness and go for proper comfortable size. You can also go for a boxer cut if you like to keep it loose, but it can also rub against your skin too much and chaff.

So, we recommend you to go for a pair of underwear that offers a slight snug fit and have enough room for breathability and ventilation.

Design And Construction

For a comfortable hiking experience, you should go for an underwear design that has got flatlock seams. Flatlock seams are more preferable because they have a smaller surface area. This ensures that you experience minimal fiction against your skin resulting in a reduction in the risk of bruising as well as chafing.


It’s obvious that we all need apparel that is durable and long-lasting. We don’t want our underwear to tear in the middle of our hiking adventure. We want a product that can withstand the vigour of high-intensity activities and heavy washing too. But, durability is one of such areas where you will have to make a trade-off. If we compare natural and synthetic fibers, the synthetic ones are much more durable. Synthetic fiber underwear can hold well even after rough and extensive use. However, this is not the case with natural fiber (merino wool) underwear. It will need specific fabric care and may fall apart earlier than the synthetic one. But, it is also true that natural fiber is much more comfortable than synthetic fiber. So, it’s your decision to make, whether you need more durability or more comfort.

Antimicrobial Protection

For hiking, underwear with antimicrobial properties can be of great help. It is because it will save you from unwanted itchiness, odor, and will give you a fresh feel for a longer period. If you are going on a trip for several days and want to pack light, then an antimicrobial undie is a good option for you. While on a trip, it is a bit difficult to wash your apparels. Hence, an antimicrobial boxer will keep you and your boys fresh and protected from germs that thrive due to sweat.

The best material with antimicrobial properties is merino wool. It is naturally antimicrobial. This means you can wear this underwear for a long period without any repugnant smell.

On the other hand, synthetic fabrics do not have any antimicrobial properties. But, they can be treated to become antimicrobial. The only drawback is that the antimicrobial coating on synthetic fibers will fade over time due to regular washing.

So, choose your underwear wisely.

Drying Period

The drying time of underwear becomes an important factor when you are traveling in a region with high humidity or unpredictable rain. Faster drying also means that your underwear should also provide you with some comfort even after getting damp.

Both merino wool and synthetic fibers feature quick-drying capabilities. The point to note here is that synthetic fibers dry up a bit faster than natural fiber. But, merino wool feels more comforting than synthetic fiber even after getting wet.

Washing Care

In the washing department, synthetic fibers have an edge over merino wool. Merino wool needs slightly more care than synthetic fibers. But, sometimes the care that merino needs is overrated. You can simply wash your merino underwear with your other clothes by being a bit sensible. Try avoiding too much hot water and wash it in cold and warm water. Merino is a bit delicate, so don’t thrash it into shreds by washing it in a fast spin cycle. Use medium spin.

We all know by now that merino has antimicrobial properties. Hence, you don’t need to wash it as frequently as synthetic underwear. Only wash merino garments when it actually needs it.

Both merino and synthetic fibers dry fast, so it will be good to air dry them. But, if you want to use a dryer, keep the dryer at a low temperature while washing merino.

And remember, you should always follow the care instructions, given by the manufacturers, printed on the packaging.


The fact that the underwear you wear is out of public view doesn’t mean that you pay less attention to it down there. You should not make any compromise with your comfort level and enjoy a reasonable amount of ease. Hence, for your hiking adventure, you should invest in a pair or two of quality underwear.
