What Type of Fabric Is Best for Hiking Underwear?


Let’s talk about the materials used for underwear that work best for hiking…

  • Synthetic Fabrics

Allow me to make it very clear that hiking underwear gets its breathability from synthetic materials. These include nylon and polyester. The less common ones being rayon and polypropylene. Then there are some undies that use spandex for a comfortable stretchy fit. Spandex also fits very snugly without feeling constrictive.

The beauty of such synthetic fabrics is that they’re odor-resistant, durable, and quick-drying as well.

  • Merino Wool

Known for its itch-free, ultra-fine, and soft quality, merino wool is a very popular choice. It’s often combined with other materials such as nylon or spandex. This special blend enhances durability, fit, and flexibility.

Merino wool underwear for hiking wicks away moisture like no other pair. The fabric is also temperature regulating. And keeps bad odor-causing bacteria at bay.

But it’s not as durable as the synthetic options. Due to the wear and tear that takes place because of constant rubbing.

What Type of Underwear Is Best for Hiking?


Should you wear briefs or boxers for hiking, camping, trekking? It’s a simple, very commonly asked question. What style of undies you wear obviously, is a personal decision to make. Only when you experiment are you able to find the actual solution for your junk on the trail.

Nevertheless, the general rule of thumb is wearing boxer briefs. It’s because boxer briefs offer the best of both worlds. That is the excellent support of briefs and the added coverage of boxers. The former keeps you comfortable. While the latter keeps you chafe-free, thus even more comfortable.

So if you end up wearing briefs for your hiking trip. The chances are you might not get enough coverage in the thighs. The outcome of this is painful chafing. And if you wear boxers, then you’re highly likely to dislike them too. Because of the lack of support. And due to the looser fit, which tends to cause the underwear to bunch up.

What Underwear Fit Is Best for Hiking?


No denying that a proper fit down below welcomes a whole list of benefits. No chafing, comfort, support, breathability, and more. So how do you go about choosing a pair of hiking underwear that fits well? Here’s the answer to yet another frequently asked question…

A snug fit, but not very tight either

Underwear that is form-fitting but, at the same time, doesn’t feel too tight. This is the kind of fit you should be looking for to prevent discomfort. However, that doesn’t mean buying a few sizes bigger than your normal size. Because if you do that, rubbing and bunching can be quite a nuisance. By causing a tremendous amount of skin irritation.

Many outdoor and fitness enthusiasts wear compression underwear. It works best for active sports. Such as working out, running, cycling, etc. So why not try out the compression fit for hiking!

But there is a downside to wearing compression underwear for too long. You might find that constant pressure a little uncomfortable after a point.

A proper fit enhances ventilation

Do you really think loose underwear is going to do a better job of providing breathability? In comparison to underwear that fits just right? I don’t think so. Let me explain.

If you want the underwear to wick away sweat and moisture. Then the fabric has to come in contact with your skin first. This means a form-fitting pair is the most suitable.

A longer cut prevents thigh chafing

Are you often dealing with chafing because of your workouts or outdoor adventures? Doesn’t matter if the answer is yes or no. Because inner-thigh chafing should be avoided at all costs. And the only way to do that is to wear underwear with longer-cut legs.

The underwear should cover your inner thighs to eliminate the possibility altogether. Such as boxer briefs. And this solution works for both men and women.

Other Features of the Best Men’s Underwear for Hiking


Now that the main aspects have been covered. Here are some additional yet equally important features that most hiking underwear designs are outfitted with:

  • Tagless

This paves the way for an itch-free hiking experience.

  • Wide, Flat Waistband

When the waistband is narrow, expect it to dig into your skin. And when it’s bulky and thick instead of being flat, look forward to nothing but discomfort. So make sure the band is wide, flat, and feels smooth against your skin.

  • Flatlock Seams

The most attractive quality of flatlock seams in undies is that they don’t press into the skin. These are wide, flat seams that prevent chafing and itching.

  • Functional Fly

Unfortunately, there are many underwear options not designed with a fly. Normally, this may be okay for some men if not most. But when hiking, camping, trekking, etc., you need that fly for convenience.

Speaking of convenience, here’s a video all avid hikers might want to watch…


A pair of high-quality underwear, no doubt, is a good hiking companion. High-performance, comfortable, breathable, and durable boxer briefs are a great choice. Such as the Adidas Men’s Sport Performance Boxer Briefs.

You can wear these without feeling any form of restriction in terms of movement. And they’re miles away from making you feel grossed out after staying on for too long. All thanks to the stretchy fabric and moisture-wicking technology.

And if you don’t like these. Then you have many other equally outstanding options to choose from. All of which are boxer briefs, thus ideal to provide a supportive fit. Along with enough leg coverage to prevent chafing.
