Check out the finest tech for stay, dry, warm and comfortable

Whether your preferred sport is hiking, mountaineering or trekking, you will agree that the sporting gear you choose to adorn has a huge part to play in your overall participation in your favorite pass time. When it comes to the outdoors, being suited in the right clothing has a great impact not only on your physical comfort but on your performance as well.

Unfortunately, outdoor enthusiasts usually spend a pretty penny on most of their clothing equipment but for some reason experience reservations on going the whole nine yards when it comes to purchasing under wear.

In our humble opinion, going for a long hike or trek with regular underwear is a self-inflicted punishment. It can be equated to going for a trek with ill fitting shoes. You can be sure the experience would be memorable for all the wrong reasons.

Understanding hiking underwear

Hiking underwear is arguably one of the most underrated pieces of clothing equipment for those who love to hit the trail (or at least for those who have not undergone through the baptism of fire in the name of chaffing and self-inflicted wedgies).

Not wearing the right hiking underwear on the trail can be a source of great discomfort and definitely takes away the pleasure of the outdoor experience. It is kind of hard to enjoy the beautiful sweeping vistas when your inner thighs are raw from chaffing or you have to attend to a wedgie every five minutes and yet you have double figure kilometers to cover.

Hiking, mountaineering, and trekking, being endurance and high exertion physical activities, need to be undertaken when one has the right clothing equipment that allows them the comfort to perform optimally and enjoy the sport in the process.

Hiking underwear that is designed and constructed to ensure maximum comfort while on the trail is of paramount importance to that equation. So what exactly is hiking underwear?

The Basics

When it comes to hiking, just any underwear won’t do. It needs to be the kind that protects you from the common underwear discomforts you are likely to face on the trail, namely:

  • Rubbing
  • Odor
  • Sweating
  • Chaffing/ Rashes between the thighs and groin
  • Lack of ventilation, causing discomfort or overheating


Hiking underwear is constructed to combat all of the above-mentioned issues ensuring each problem is addressed and mitigated. They are usually:

  • Breathable
  • Able to prevent chaffing and rashes
  • Absorbent and fast drying
  • A snug fit and adequately cover your thighs
  • Have a tight waist band is tight and hug the body without causing discomfort or cutting off your circulation
  • Made of antimicrobial textile, or antimicrobial treated textile which means your underwear will remain fresh even after several days of use

Finding the right pair for you

Finding the right fit for your expedition

What are the things to look out for when selecting excellent hiking underwear?

1. Material

The type of material used in hiking underwear is geared towards being comfortable. The materials used would be natural material like Merino wool or synthetic materials like polyester and Nylon. Usually, elastane might be added to these materials to provide better stretch and comfort.

Merino wool, polyester, and Nylon are common features in the construction of hiking underwear because they are:

  • Breathable
  • Moisture wicking
  • Quick drying

These properties help to effectively maintain your body’s natural temperature. The choice between the two can be a bit hard to make owing to the similar comfort levels. However, while both of them are exceptional choices, they do differ in benefits and a user would need to thoroughly weigh which benefit they need most.

Merino wool

Merino wool is considered more versatile because not only is it suitable for cold weather, it can also be used in warm summer days as well. This is because merino wool can be processed into very thin fabrics or a thicker construction.

Merino wool feels pleasant to the skin and is naturally antimicrobial with breath-ability that is far superior to synthetic fabrics. Most importantly it provides warmth even when soaked with sweat.

Synthetic material

In the case of synthetic hiking underwear, it is inexpensive and is known for a quicker dry time in comparison to merino wool. It is also definitely more durable.

2. Drying time

This is a very important factor that must be considered especially if you are packing light and will be on the trail for several days on end with the same underwear having to last you for the length of time you are out there. It is also something to consider if your terrain involves being in and out of the water. In both instances, a fast drying material ensures you are comfortable sooner.

Synthetic materials are fast drying with polyester and Nylon hiking underwear leading the pack. Both materials are remarkable in how fast they can dry and are excellent options in this regard.

3. Construction and Durability

One thing you can be sure of on a lengthy hike is that your underwear of choice will be put to the ultimate test. This is not the time to bring out your luxury brands. They are counterproductive as they will start falling apart midway through the hiking expedition.

An important aspect to check for in the construction of hiking underwear is the presence of flat lock seams. These are key to enhancing comfort and reducing chaffing. It also does not hurt to check if the garment used in construction can be machine washed without damage.

4. Style

Hiking underwear comes in different styles and sizes to suit all types of physiology.

Some guys might prefer boxers, although men with powerful thighs have reported experiencing chaffing with boxers. If you are prone to chaffing, which is a most disconcerting issue on the trail, our recommendation would be boxer briefs.

It is almost unanimously believed that boxer briefs are the best style to go with as they have a tight fit which serves to transport perspiration from the skin to outer layers and provides extra coverage on the thighs that prevent chaffing.

The ability to buy good hiking underwear lies in ticking off all the above important qualities. However, the question is whether there is hiking underwear available on the market that epitomizes all these crucial elements and achieves the perfect balance of durability and comfort.

Below we take a look and examine some of the best men hiking underwear in the market today to see which one meets our requirements above
