Keep the elements out and the heat in with Heat Holders Snowday Performance Mittens for Kids. Every part of these protective, shower- and wind-proof mittens protect small hands from cold weather. The plush and soft HeatWeaver linings provide soft comfort and maximize the amount of warm air that's held close to your child's skin, while the additional Thinsulate insulation (65% polypropylene/35% polyester) and filling (100% polyester) provides extra warmth and breathability. The knitted cuffs seal in the heat, hook-and-loop fastening straps and roller system create a custom fit, and there's a special, textured grip (100% polyurethane) on the palms. These Heat Holders toddler gloves are constructed from 100% polyester with 99% acrylic/1% elastane cuffs. Hand wash only. Imported.Manufacturer style #: HHG07320.
