All No Fly Zone 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 the No Fly Zone Boulder lowers your chances of getting bothersome bites - or worse, insect-borne diseases - on your next day hike or backpacking trip.
U.S. Merino Wool
Merino wool is soft, itch-free, naturally odor- and bacteria-resistant, cool in the summer and warm in winter. We source our 100% U.S. grown merino wool exclusively from sheep raised by American farmers on American farms.
