5/A Baker® Medium Weight 200g Turnout Blanket is both waterproof and breathable. Features include 200g Curvofil IV insulation, gusseted shoulders, bias surcingles, elastic leg straps and a tailpiece. The outer shell is a 1,500-denier polyester rip stop fabric that can take an incredible amount of abuse while the satin smooth lining polishes the horse's coat. A waterproof/breathable membrane bars water penetration yet allows water vapor from perspiration to pass through to the outside, keeping the horse warm, dry, and comfortable.
