Factors To Look For When Buying Best Hiking Underwear

Now that you have the list of the best hiking underwear, it is also important that you figure out what specifications suit you the best. Some criteria need to be ticked off before you buy the ideal pair of hiking underwear. Let’s check these out one by one. 

1. Material

Choosing the right base layer material is of utmost importance because your comfort, for the most part, rests on that. You mostly have two options when it comes to the fabric—synthetic and wool.

Merino wool is considered the ideal option for underwear material as it is organically occurring, soft, and naturally odor-resistant. Its strands are extremely thin and provide you with utmost comfort, almost as if it’s just a second layer of skin. It has great moisture-wicking properties and feels nicer against damp skin compared to synthetic materials. 

Merino wool also brings with it thermoregulatory abilities, so that you remain warm during cool weathers and vice versa. This material is usually combined with smaller compositions of synthetic fibers to get the best of both worlds. Also, pure merino wool would be very expensive to get your hands on compared to synthetic fibers.

While we keep that in mind, it should be noted that generally, synthetic materials are preferred because they’re available at a cheap rate. These could involve nylon, polyester, spandex, rayon, or a combination of any of these. Synthetics are also more durable. They’re easier to maintain and dry faster than merino wool. However, they feel very mushy against damp skin and this might cause discomfort especially when you’re hiking or performing high-intensity activities. Also, they’re bad at odor-retention, especially compared to merino wool. 

For many people, cotton seems to be the only fabric their skin is compatible with. However, cotton can work pretty bad when there’s a lot of moisture involved, as it cannot hold excess moisture. Even if it does hold too much moisture, it eventually becomes heavy and then ends up chafing against your skin. It would also take a long time to dry, and that is a big no-no when you’re looking to enjoy your hike. 

2. Style/Cut

Very tight-fitting hiking underwear might cause discomfort regarding breathability and can also increase the chances of chafing, especially when you’re out hiking or doing any kind of athletic activity. It is thus important to get a relaxed fit of underwear, but a pair that is too loose can also cause chafing and irritation.

There are three basic styles of men’s underwear—boxers, briefs, and boxer briefs. Though briefs provide good support, coverage becomes an issue and can cause chafing, especially on your thighs. In this case, it is best to switch to boxers or better yet, boxer briefs.

Boxers give you a looser fit and more airflow, keeping you comfortable and snug. However, you do need to take care that they don’t become too loose and end up bunching. Bunching can cause a lot of discomfort and hamper your movements when you’re performing any activity. A loose fit can also prevent the fabric from wicking the moisture away from your skin.

Boxer briefs seem to be the best option because it provides a comfortable fit as well as good coverage so that chafing could be avoided altogether. It also gives more support and keeps you snug throughout the day.

3. Tagless Underwear And Flatlock Seams

It can get extremely irritating when the tags on your underwear rub against your skin. Even walking becomes difficult in this case, let alone hiking. Tagless underwear is thus the new sought-after thing.

The same idea lies behind flatlock seams as scratchy seams can cause much irritation to your skin and can even cause cuts. Flatlock seams are wide and comfortable as they don’t press against your skin.

We advise you to look for underwear with both these features because believe us, they’ll make a massive difference.

4. Odor-Resistance

Often overlooked, odor-control is a very important factor when it comes to buying hiking underwear as hiking demands you to stay outside for a long time, possibly without a change of clothes. It is thus vital that your underwear remains fresh and does not stink. 

Merino wool is naturally odor-resistant and thus comes highly recommended in this case. Some synthetic fabrics come with antimicrobial treatment to control odor but this works only in a limited number of cases as they usually fade after repeated washes. 

5. Wash-Care

It would be quite disappointing if you ended up with holes in your underwear just after a few washes because you didn’t follow the washing instructions correctly. Most of the time, you could throw your underwear in the machine and get it cleaned. But during hiking, you must be able to wash your underwear at the sink and get it dried quickly as well. 

Both merino and synthetic fibers dry pretty quickly, so you need not worry about that. But do keep in mind that merino fibers get ruined if you don’t wash them at low temperatures. Also, while drying your hiking underwear, make sure you avoid direct sunlight as this can cause unnecessary stretching of the material.
