6 Factors: Choose the Best Underwear for Hiking

There are a number of factors to choosing the best (most comfortable) underwear for your next hike. Ignore one and you might regret it. Let's get started!

1. Material: Synthetic vs Wool

What it really comes down to is synthetic versus wool. As a rule, no cotton should be worn as a base layer of any kind. Why? Cotton soaks up sweat, and does not dry quickly. The results are chafing, discomfort, and potential infection.

Both synthetic and wool do a good job of drying quickly, breathing, and moisture wicking. However, there are some pros and cons to each. Merino wool underwear stays warm when wet, offers breathability, and acts as a natural microbial. Synthetic undergarments are typically less expensive, much stronger, and faster drying.

2. Flatlock Seams

Flatlock seams are a must on the best underwear for hiking. If your seams are sticking out, they will rub uncomfortably on your nether regions and cause chafing. In addition, you won’t want a seam that runs down the middle of the underwear. Over time this will cause discomfort.

3. Antimicrobial

The best underwear for hiking will have antimicrobial properties to keep bacteria in moist areas under control. As mentioned, merino wool is naturally antimicrobial. However, not everyone likes the feel of this material.

Synthetic materials are usually treated to give them protective properties, though these will get washed out eventually.

4. Durable

You will want to find underwear that is made to last. It is important that whatever products you chose will hold up during machine washing. If your unmentionables begin to lose their form, they will also become uncomfortable and cause chafing and bunching.

5. Moisture Wicking

It is important to choose underwear that has moisture-wicking properties. This means the material will naturally pull sweat away from your body while you are hiking. Moisture wicking will help you stay dry and clean during your adventures. This can feel like a lifesaver during hot hikes.

6. Breathable

Material breathability is also important when deciding on the best underwear for hiking. There are many reasons this factor is key. The more the undergarment is able to allow air to pass through, the faster it will dry. The faster it dries, the less likely you will feel uncomfortable. Not only that, but the more breathable the underwear, the more free and breezy you will feel down there. Your skin will thank you for helping it do what it needs to regulate your body.
