Don't let the flies and chiggers make a snack out of your ankles. BugsAway® rebuffs their advances and lasts through 70 washes for full-season protection. A wicking woold blend and arch support make this the hiker's dream sock. Bug blocking: BugsAway® apparel is treated with Insect Shield®, giving you invisible, odorless protection just by putting on your clothes. The treatment is bound to fabric fibers, so it stays in your clothes—not on your skin—and lasts through 70 washes. Ants, flies, chiggers, midges, and ticks don't like it, and neither do mosquitoes, which can transmit insect-borne diseases such as Zika, Chikungunya, Dengue, and West Nile viruses.
