The Spyder Boys' Propulsion Pant is a snow pant for trying out skiing, snowboarding, sledding and after school snowball fights. PrimaLoft Black Eco insulation, 60g of it, adds enough warmth to maintain comfort on a cold day, while the stretch recycled Repreve polyester fabric with 10k/10k laminate provides movement-friendly, waterproof, breathable protection. Layman's terms? Your kiddo stays outside for longer, having fun, dry and comfortable. The suspenders are removable and adjustable so they won't slip off and down at the cuffs, internal snow gaiters prevent snow from sneaking its way inside. When the season is over, save them for next year as the Room to Grow Hem feature extends an additional two inches.
