The BROWNING Merino Hooded Shirt is the ideal foundation for warmth. Itch-free, 100% Merino wool is warm, wicking, dries fast and is odor resistant, making perfect to wear next to the skin as a base layer. The 1/4 length front zipper makes it easy to cool off under exertion. Conversely, the fitted hood traps in heat to help keep you warm on the coldest days.
