From snowman building to sled-hill trekking, the Kamik Penny 3 Boot keeps our little's toes toasty with synthetic fill holding in warmth, a fleecy lining wicking away moisture, and an impermeable build stopping snow and slush from seeping in. With a slip-on design and an easy-grab collar cinch and ankle strap, this pair is easy for our little to get on and off on their own.
