These wool hiking socks feature No Fly Zone technology that repels ticks, black flies, mosquitoes and more. Made with responsibly-sourced Merino wool, they're perfect for hiking, trekking into town or just about anything outdoors.
Don’t let biting insects keep you from getting outside. Our No Fly Zone collection is treated with permethrin, a synthetic form of a naturally occurring bug repellent, so you can be free of biting insects – including ticks, black flies and mosquitoes. Permethrin has been proven effective at repelling biting insects, helping you keep free of itchy bites. The Merino wool is RWS-certified so you know it was harvested in a responsible and sustainable manner.
