These Farm To Feet Unisex Boulder No Fly Zone Lightweight Crew Socks are manufactured using yarns treated with permethrin insect repellent. Odorless and durable, permethrin repels common biting insects like mosquitoes, flies, chiggers, midges, ticks, and ants. And best of all, it doesn't alter the amazing qualities of our 100% US-made Merino wool. Wearing these insect-repellent socks lowers your chances of getting bothersome bites or insect-borne diseases on your next day hike or backpacking trip.
