Revel IV High Polar: A showcase of KEEN technologies
If there is ever a brand that takes homegrown tech seriously, it would have to be KEEN. The Revel IV High Polar is a testament to this with the following:
KEEN.WARM: At 400 g, this insulation will ensure sufficient warmth up to the lower calf in below-zero conditions. This tech coupled with the boot’s heat-trapping insole translates to cozy hikes for many hours!
KEEN.DRY: The Revel IV High Polar is fully waterproof because of this. Since the boot in question has a high clearance, a gaiter is not required to keep your tootsies dry in, say, 5 inches of snow.
KEEN.Polar Traction: This exclusive outsole provides high surface traction on icy surfaces. Engineered for frigid conditions, this rubber component does not freeze easily, keeping its effectiveness intact in extreme cold.
