Best Underwear for Long Hikes

When preparing for a hike or backpacking trip, the first thing to attach itself to you will be your underwear. It’s important to note that your underwear is next to the skin base layer; thus, it needs to function well. This underwear should be breathable, moisture-wicking, fast-drying, and ideally should not feel damp or cold when wet.

It is also good to note that good hiking underwear is designed to prevent chafing, and if your underwear does chafe while you are hiking, your hike can become uncomfortable. This might also cause blisters on your groin. Hence you should choose underwear that is built to avoid.

Additionally, with any technical clothing piece, deciding what is the right underwear depends largely on where you will be hiking and in whatever season.

In this article, we have researched and prepared a list of all things you need to consider when buying hiking underwear; additionally, we have prepared our favorite list as tested by our experts.

But before we dive into the list, let us first discuss different types of hiking underwear fabric in the market today.

Synthetics: These are breathable underwear for hiking made from synthetic fabrics. Examples are polyester and nylon. However, these are not the only ones, as you can find polypropylene, rayon, or a blend of materials. Underwear made from synthetic fabrics has the following features:

  • They dry a bit quickly as they efficiently dissipate sweat, thus giving the driest feel
  • They are durable
  • The synthetic fabric holds onto odors more than other options.

Merino Wool: Soft, ultrafine, itch-free merino wool is an excellent option for underwear. It’s also blended with other fabrics, like spandex or nylon, to enhance fit, flexibility, and durability. Underwear made from merino wool has the following features:

  • Wool does an excellent job of pulling moisture off of your skin and into the fabric
  • The moisture that is held in the core of merino wool fibers releases when the temperature heats up.
  • This underwear is less durable as constant rubbing can eventually wear out
  • These underwear are naturally odor-resistant.

David Archy Performance Hiking Underwear

David Archy Performance Hiking UnderwearAnother great option for affordability, this pack of three boxers is the least pricey on this list – and you get three of them! They come in 16 different color choices.

They’re also an excellent choice for versatility – they come in three different structure options: mesh with no fly, mesh with the fly, and solid with no fly.

Because these are more affordable, they are, of course, built with lesser quality. They aren’t Merino Wool. Instead, they’re made with polyamide and spandex.

Even though they’re of slightly lesser quality, they still perform surprisingly well for the price point. They’re breathable, they’re fast-drying, and they have a roomy crotch. They have a snug fit, and the build is pretty good at stopping you from getting too sweaty.

There are no antimicrobial properties here, and they have a habit of bunching up, which isn’t great for a hike, wildly if you’re scrambling. The sizes are also a little off.

Features

  • The 3D pouch is extra roomy for allowing more excellent lower-body movements
  • The stitching is flat and seamless to keep chafing at bay
  • The seamless hip design embraces your hips completely
  • Provide total comfort
  • fast-drying fabric
  • It’s the high-technology

PROS:

  • Fast-drying, breathable fabric.
  • 3D pouch for freedom of movement.
  • Snug yet comfortable fit.

CONS:

  • Too thin and lightweight material.

 

Buying Guide for Best Underwear for Long Hikes

You need to make sure the underwear you’re buying is comfortable! If your underwear is uncomfortable, so too will be your walk. Many new hikers underestimate how hugely important underwear comfort is – don’t make the same mistake!

You need to ensure that your underwear doesn’t chafe or leave you sweaty. It’s therefore essential that you go for materials that are breathable and have a quick drying time.

Here are factors you need to consider:

Durability

You don’t want your underwear to tears while you’re hiking. And you don’t want to keep replacing it. You want to ensure your underwear can withstand heavy use and heavy washing. If your underwear is well-constructed, it will be much more durable.

Washability

It’s important to wash clothes as instructed. If you don’t, they’ll fall apart. So don’t buy underwear with precise washing needs.

Instead, you want something that can be hand-washed and simply machine-washed. You also want to go for the best hiking underwear, which is quick-drying, so you can dry your smalls during the night while you’re mid-hike.

Cut And Construction

Some people prefer boxers; some people prefer briefs. Neither is objectively better than the other from a hiking perspective, but you should wear whatever you find most comfortable.

You also want to ensure that you buy underwear that’s well constructed. Well-constructed underwear won’t slip around, and it won’t chafe.

You might also want to consider the type of fly opening you like. A good fly opening is handy, so you can take a pee without pulling your underwear down.

Fly

This is similar to what you would find when it comes to regular underwear that you buy, but it is still important to figure out whether the underwear has a fly.

Some guys do not care whether there is one or not, but it can be a make or break feature of their underwear for a lot of guys. If you want a fly, make sure to check that before you go ahead and buy a pair.

Drying Time

With almost all types of hiking underwear, you’re going to find that the material will dry a lot faster, which is great because if you happen to get wet, you need them to dry out rather quickly.

If you buy quick-drying underwear, you’ll have a much easier time washing your garment while on the go and have complete confidence that it will dry in no time.

Travel Capability

While this might not be an essential consideration for a lot of people, it’s something you need to consider if you are backpacking and want to try and take as little with you as you can.

While most of the difference is going to be minimal, it’s worth noting the underwear’s weight if it matters to you. Fortunately, most of the materials used for this underwear are lightweight, so that it won’t be much of an issue.

Final Thoughts

Our favorite underwear from this list is the SmartWool 150. Yes, they’re a little pricey, but they’re otherwise fantastic. And the price point is justified in performance and quality. They’re comfortable, they’re durable, and they’re crafted from Merino Wool.

After reading everything there is to read about the best hiking underwear, you’ll have no problem finding the best underwear to meet all your needs.

You will not only know what you need to look for when it comes to finding underwear, but you’ll also have some of the best product recommendations that you can find, so you get a great pair.
