Best Hiking Underwear: Comfort All the Way

Written by Kane Dane

Hiking underwear is not your usual type of underwear as you have already assumed. You will agree with us that winter hiking underwear especially is an essential part of every hiker’s gear. Everyone who thinks otherwise hasn’t tried a high quality hiking underwear yet.

This type of underwear is an underestimated piece of the hiking gear. A hiker would spend a relatively large amount of money on other pieces of equipment, and when it comes to underwear, we are always holding back.

It seems that most of us tend to forget that, when you are hiking or doing some other outdoor sports activity, the underwear is the basic layer of clothing which should help you feel good instead of sweaty and wet. Therefore, this type of underwear is specifically designed to enhance the performance by letting you focus on the sports activity instead of your personal discomfort.

This is why you need to make some time for doing the research on the important features a hiking underwear should have. Or you can simply sit back and read through this buying guide and choose the best hiking underwear for your needs.

Features to Consider Before Buying

Several things should be taken into consideration before choosing underwear for your trip, and these are:


This is usually the first thing you should consider when buying any equipment which comes in touch with your skin. The general rule is that if it comes in touch with your skin, it goes into the basic layer of clothing category, making the material the most important feature.

When speaking about hiking gear, the rule applies too. The material should be comfortable and have a high functionality of maintaining your body temperature.

This means that a winter hiking material should keep you warm while allowing your skin to breathe. It is also recommended that your material is quick drying, since this is quite important up there.

In hiking underwear, merino wool is the leading material feature. It has all the required characteristics: a natural material which is allowing your skin to breath and it is also known as a material with highest warming properties.

However, the main downside to the wool is that it is relatively expensive and it is quite often out of our budget limits. The alternatives are synthetic materials or a blend with wool and a synthetic material.

When it comes to synthetic materials, in order to keep up with the competition, they are sometimes treated with antimicrobial agent. This is done in order to avoid building up the bacteria which most often occurs when sweating.

This is also the main reason why sometimes the human sweat smells bad. Merino wool, however, has natural antimicrobial properties and there is no need to be treated with anything. It is also extremely lightweight; and as every hiker knows, every pound matters.

Merino wool Underwear

The popular underwear materials in the synthetic world are polyester, which is most commonly used, and lycra, which is a stretchy material most often combined with wool or other synthetic blends.

Material care and washing

This is often an underrated feature; especially if you have someone else doing this work for you. For all of you who don’t, keep in mind that hiking underwear should always be quick drying. It is best if the hiking underwear is machine washable, but it is not a big deal if you have to wash it by hand.

underwear washing in machine

Some synthetic materials, which are treated with antimicrobial agents are recommended to be washed by hand or on low temperature because there is a danger of losing the antimicrobial properties otherwise.


The only way to know the durability of a piece of equipment is from someone who has already experienced the product. For this reason, we have reviewed and tested all of our products and we are sharing our experiences with you. When it comes to durability of a hiking underwear, the synthetic materials are more durable.

It is not that the wool material is not durable, but it tends to change over time, unlike some of the synthetic blends. With regular washings every material loses its original form. This is especially true for antimicrobial treated synthetic materials since they lose their antimicrobial properties after around 6 washes.


This feature usually goes with the user’s taste. However, the main reason it is included in the “things to consider” list is because of the thigh chafing in certain people. If you find yourself among these people, make sure you order a stretchy underwear which perfectly fits your thighs.

This should take care of the problem even though you are hiking in warm weather, and let you enjoy your hikes without any worries or pain.


This is a contradictory feature and you should balance between your needs and the offer on the market. Looser underwear creates more chafing as we mentioned before. However, it also allows better ventilation and skin breathing, especially in the warmer days.

Tighter fitting on the other side are perfectly good against chafing, but they could be less comfortable and the skin breather harder through them since there is no airflow. This is compensated by the breathable materials, but on warmer days, even these materials can’t help.

Amount of the material

Has it ever happened to you that you order a material thinking it is with high quality, but instead you got exactly what you described only much thinner? The amount of material used for manufacturing the product matters a lot, especially in winter conditions.

If you are paying for a high quality Merino wool material it is only fair to get it right. For this reason, we have put this feature in our search characteristics and eliminated all materials which were too thin. However, keep in mind that thicker materials have also higher weight.

This is why we recommend you always checking and comparing the weight of the material with its competitive products; it can give you a lot of information.

  • I’ll admit to clicking on this article for the picture at the top, haha. But I think I found the perfect gift for my boyfriend’s birthday! We hike together pretty often and he’s complained about sweaty underclothes a few times. Are the Under Armour boxer shorts the only ones with moisture-wicking on this list?

  • There are lots of comfortable-looking options on this list. I need some new hiking underwear and finding this site has been a big help. I like seeing the most popular items along with underwear that has a great value. This has given me a lot more places to look while I shop. Thanks!
