It’s also moisture-wicking, quick-drying, and it’s made with anti-odour technology that actually prevents the microbes that create the stink from even growing. Under Armour gives this gaiter strategically-placed ventilated spaces for bonus means of cooling. With silicone strips on the back interior, the gaiter can secure its position on your head or a hat. Designed to flair out at the bottom, the Iso-Chill gaiter will fit right over where the base of your neck meets your shoulders.
