evo.com | Outdoor Research Balaclavas > A 75D stretch woven fleece with a grid interior gives the Outdoor Research Vigor Plus Balaclava serious warmth without the bulk of a heavier knit. The recycled polyester and spandex blend moves with you and wicks sweat on the skin track, while a hinged design lets you dial coverage up over the nose or down around the neck as conditions shift. It layers flat under a helmet, so it works for cold laps just as well as cold commutes.
