A proprietary waterproof, breathable membrane that lets vapor out without letting water in.
KEEN.WARM
Our signature insulation is extremely compressible and light for the foot warmth it provides, and it retains its insulating ability, even when damp.
Care
Gently brush the footwear with a soft bristle brush or hand towel to remove loose dirt and debris. Stains can be treated by lightly rubbing a gum eraser in a circular motion over the location and lightly brushing afterwards. Tough stains can be treated with a mixture of water and a little vinegar on a damp cloth. This process may cause slight discoloration to the area.
