Whether navigating a dark timbered hole on a snowmobile to track a cat or waiting on a sopping wet Brooks Range ridge for a bedded ram to stretch its legs, having warm hands is non-negotiable. Built for the harshest conditions hunters encounter, the Altimeter Mitts boast waterproof 3-layer HydraShield shells and removable PrimaLoft Cross Core synthetic insulation liners, providing uncompromising warmth and protection from wind, rain, snow, ice, and relentless cold.
