How to Choose the Best Men’s Hiking Underwear

Hiking in the colder weather doesn’t have to be a miserable experience. Often, the combination of activity making you sweat and the cold air makes it an extremely uncomfortable activity. But if you love to hike, you’re going to love our hiking underwear buying guide! Investing in these special clothes can make your cold-weather hikes much more comfortable and enjoyable. But before we get started, here are some things you should know in order to start shopping.

Type: This refers to what type of garment the product is. This might be a thermal shirt, a pair of thermal pants, or a set that includes both a shirt and pants. It depends on what you prefer.

Age: Is this an adult-sized product, or a child-sized one? The same hiking underwear garments that men use for hiking are often used as long pajamas for the wintertime, so make sure that you mind this when you order.

Material: What are the garments made of? Cotton helps keep you dry but is less flexible than spandex. Polyester does a good job of being both breathable and stretchable. Most products on this list are a blend.

Color Options: You can also use most of these for outerwear, and that’s where this option comes in handy. This is the number of different colors and styles that you can order, and it’s mostly down to preference.

Size Range: This is the range of sizes that you can order these clothes in. Most have a wide variety so you can make sure to get the perfect fit for your hiking underwear. Always check the sizing charts, though!

Machine Washable: For the most part, these clothes can be washed in a washing machine. A small portion of the might not be able to handle the intense agitation and will need to be washed out by hand.
