The Snow Pile One-Piece Snow Suit uses behind-the-knee articulation and a gusseted inseam built for serious play, so a toddler can crawl, climb, and roll through the snow without the suit fighting back. A waterproof, breathable H2No Performance Standard shell keeps them dry through it all, and 100-gram Thermogreen insulation adds warmth without slowing down their movement. What Our Gearhead(R) Experts Are Saying:"My toddler crawls through snowbanks and climbs onto everything within reach, and this suit moves with her the whole time instead of riding up or pulling at the knees."
