Made with seam-sealed waterproof leather and a warm, recycled felt inner boot that is comfort rated by Sorel to 40 below zero, the Yoot Pac TP Boot is ideal for building snow forts, sledding, or helping shovel the driveway. Its waterproof construction sheds moisture to keep their feet dry as they hike up a snowy hill or walk through slush on the playground. A recycled felt liner and bonded felt frost plug provide insulation that keeps their toes nice and warm on the coldest winter mornings. This recycled felt liner is removable and washable as well to keep their feet fresh throughout the season.
