Some might ask if people really need technical underwear to go out hiking, climbing or skiing and my answer would be that if you don’t get any other kind of “outdoor” gear, the right underwear is basically essential. I say that because you really don’t want to be out in the woods with underwear that doesn’t dry when it gets wet, on a mountain with underwear that doesn’t stretch around as you are climbing, or on a long trip with underwear that you can’t easily clean.
The ExOfficio Men's Give-N-Go Boxer Brief tackles all of these problems. The briefs are comfortable, well made and do well in the outdoor world.
Made from nylon and spandex these are synthetic briefs and that synthetic fabric is what gives the briefs their characteristics. They come in all the typical sizes, from small to extra-extra large. Check the tag, which correlates those sizes into waist sizes.
