Constructed with a 3-layer laminated material, developed by Revelate, composed of outer shell, foam for stiffness and insulation, and thin fleece against your hands. Williwaws maintain their upright position on the handlebars and don't flop around or sag. The exteriors are burly - bash through frozen brush and branches all you like.
The included bar end attachments internally fix the mitt to the ends of the handle bars and allow for quick, tool-free removal while preventing the pogies from sagging when loaded up on rough terrain. No fiddling with a 3mm hex when you want to take them off.
A zippered front vent with water resistant zipper allows you to blow off excess heat, a big perk on long climbs.
