Designed for comfort and maximum protection from snow and water, this is Kahtoolas take on a traditional mountaineering gaiter and one that youll actually want to wear! Ballistic nylon lowers are tough as nails for standing up to repeated strikes from traction or hiking crampons, while three-layer Gore-Tex uppers provide breathability and lightweight protection from the elements. And for added protection from rough terrain and traction strikes, NAVAgaiter features Kahtoolas new Aegis rock guard and redesigned DuraLink instep strap, so you can take on the toughest challenges with confidence.
