Overview:This is the COLDPRUF Classic Merino Wool Base Layer. This is for men and it’s 100% Merino wool, it’s a silk weight Merino wool and I think it’s about a 5 ounce weight. Keeping in COLDPRUF’s tradition all the technical features that you’d expect, the flat lock seams, a tagless design, drop tail so it stays tucked in when you’re being active, self fabric cuffs, a little bit longer sleeve so they don’t ride up on your when you’re being active outdoors. The advantage of Merino wool is that it’s quick drying and has excellent moisture management properties to it, so if it does get wet it’s going to dry fast and move the moisture away from your body and help keep you nice and warm. The bottoms are pretty interesting, it’s a got a nice 1” comfort waistband. The men’s have a gusseted crotch which is something you unique for COLDPRUF that you won’t see everywhere and that makes them very, very comfortable when you’re being active and you don’t get them riding in the places you don’t want them riding into. Again the flat lock seams and tagless design and the self fabric cuffs. These come in commando which is the color you see below and in black. Crew neck for the men only.
