These may be the most comfortable socks you'll ever own, featuring cushioning at the ball of your foot and your heel. But what really sets them apart is they’re insect repellent. The yarns are treated with permethrin, which is odorless and durable, and repels mosquitoes, flies, chiggers, midges, ticks, and ants. Wearing No Fly Zone Boulder reduces your chances of getting bothersome bites—or worse, insect-borne diseases—on your next birding adventure. These socks are manufactured with 100% US-made merino wool. The socks also feature nylon and spandex for cushioning and to allow for stretch. They're available for men in sizes medium, large, and extra large.
