OK, it is the underwear section, but let's look at this honestly; this stuff is purely for business. These are the important base layers that will keep you warm out on the trail by way of anti-wicking materials and use of the best quality fabrics. It is super important that you have a really good base layer working for you, especially when things are looking a little chillier out there. We've got some casual pieces and some that are for your more demanding day trips.
