What is the Best Underwear for Hiking?

Underwear designed for hiking should be made from high performance materials. Here is what to look for:

* Breathability

* Moisture wicking

* Quick drying

* Anti chafing

When you hike, certain parts of your body sweat more, including the groin area. This makes it essential to wear moisture wicking and breathable underwear.

Wearing underwear that pulls moisture away helps prevent irritation, odor and bacteria that thrives in warm, moist environments.
