Men's Inversion Heavyweight Merino Wool Base Layer Crew Shirt



Praised by Men's Journal and Backpacker Magazine, our Inversion Base Layer Top is made for cold weather. This 100% Merino wool long sleeve shirt feels amazing on your skin and keeps you warm without adding bulk to your layering kit. It's cut long so it stays tucked in. Discreet thumb holes keep your sleeves in place and disappear when not in use. Merino wool breathes well and doesn't hold odor, so you'll still smell fresh at après and can get multiple days of use before you need to wash it. Pair it with our Inversion bottoms in full length or 3/4 length.
