The Llano Quarter Zip is your next-to-skin layer for any activity. Made from 100% pure Merino Wool, the Llano QZ keeps you comfortable in both hot and cold temperatures. Merino is naturally antibacterial–it can’t hold on to those stinky little bacterial cells that cause you to stink, so you’re good to go for multiple days in the field when you can’t exactly grab a hot shower. Merino is also UV absorbent which means it absorbs light instead of reflecting it, keeping you dull instead of shining in the field. The Llano QZ is the quarter zip version of the best selling Merino base layer in the market.
