Because its made from merino wool, not only does it regulate temperature really well, but its odour resistant toomaking it particularly good for long hikes where youre going to be away from a washing machine for a while. As with everything from Yamatomichi, a lot of thought has gone into the shape tooand that wider, boxy fit makes it a lot more wearable than the more fitted merino base layers around.
