Description

When it's really cold out, our Inversion Base Layer Shirt is what you need. This 100% Merino wool base layer top is warm and soft but still breathable, so you'll stay comfortable no matter where the day takes you. It feels great on your skin, has a slightly longer cut to stay tucked in, and features discreet thumb holes that blend in when you don't need them. Merino wool naturally resists odor, so you'll be stink-free at après, and you can wear this top multiple times before washing.
