1200 Denier 70 Denier Inner Shell Wither fleece Adjustable leg straps Double buckle front Two surcingle and belly straps Ideal for temperatures 40-50 degrees Our turnout sheets are water-resistant, made from tough 1200D ripstop polyester to repel moisture in light to moderate weather. Because horses roll or lie down, water can sometimes get underneath, which can make it look like the sheet isn’t waterproof — but the material itself does resist water very well.
