Outdoor Research Stamina Gaiter™:
Trail running on wet or snow-covered terrain can pack your shoes and socks with ice or dirt in a hurry. The lightweight Outdoor Research Stamina Gaiter™ easily attaches to most running shoes and keeps trail crud where it belongs: on the ground. Silicon panels on the stretch fabric body shed snow and water, and the durable, breathable fabric is so lightweight you’ll forget you’re wearing these running gaiters before you’ve run more than a quarter mile.
