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.
Cushion that is light in weight along the base of the foot only. This all-season construction is highly versatile.
Traditional sock height that fits firmly on the lower calf, also known as the daily.
Seamless Toe Closure
Advanced knitting techniques create a totally flat connection in the toe box, reducing bulk and eliminating blister-generating friction.
Reinforced construction and low-stress seam placement reduce wear and tear, increasing the life of the sock.
