This Buff Bandana is infused with insect protection that repels annoying biting (and possibly disease-transmitting) insects, including mosquitoes, ticks, ants, flies, chiggers and midges/no-see-ums. You can wear this stretchy, stylish fabric loop as a headband, bandana, scarf, cap or sweatband. It keeps your hair out of your eyes, soaks up perspiration — and looks great, too! Lightweight, microfiber polyester is soft, cool, breathable and dries quickly. The fabric is treated with Insect Shield, a safe, effective and odorless EPA-registered insect repellent called permethrin that lasts through 70 washings.
