The inside of the Premium Midweight Jacket uses polar fleece lining inside the collar and body, and 60gsm woven insulation in the sleeves, keeping you warm through the winter months when you'll be at the rink or on the pond. Made from 100% polyester and 80gsm, this jacket repels water and prevents static cling, and features strategically positioned CCM logo. And don't forget the premium fabric material used on the outside of the jacket, giving it a leg up on many midweight models.
