The Hike+Liner Crew is an ultralight yet durable liner sock made with a stretchy merino wool blend that's breathable and naturally odour-resistant. Anatomically sculpted for a precise fit, this sock features key support zones in the Achilles and instep to help keep the sock in place. Reinforcements in the heel and toe help enhance durability, while the seamless toe helps reduce bulk and friction for added comfort. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino wool is an annually renewable fibre that naturally resists odors, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
