When you need the ultimate turnout, this is the sheet for you. Integrity Linens has used the technology of Sympatex fabric to design a waterproof/breathable sheet. Sympatex fabric works with your horses body heat to absorb moisture and expel it outward through the fabric. With the use of seam sealing tape, to seal all needle holes , we have designed the sheet to repel water from the fabric with the results producing a waterproof / breathable sheet. We have used the 1000 denier nylon for the outer shell for rugged durability, the middle layer is the Sympatex and the inside layer is a strong durable cotton. Standard features include contoured rump to help prevent slippage, bottom surcingle, detachable leg straps, fleeced withers and two surcingle front closures. Our favorite little guy " Blake" is modeling the Sympatex sheet shown in black with kelly trim and white piping.
