Whether you’re taking it easy on the couch or camping in the woods, comfy socks make every day better. Cotopaxi’s Libre socks are crafted from a breathable yet warm llama fiber and nylon blend. At the toe, heel, and midfoot, Cotopaxi’s bolstered the Libre with hard-wearing polyester. We’ve been testing the Libre’s for a year now and worn them on countless hikes and chilly trail runs. If we’ve learned anything over the past year of testing, it’s that nothing beats sliding these socks on to warm up after a frosty surf session. Furthermore, after a year of solid use, they’re still in good shape, and they still spark a smile every time they’re pulled out of our sock drawer, backpack, or duffle.
