Constructed with Nylon spandex for correct fit, unsurpassed in quality. The face is made without a center seam allowing for a more sculpted fit, keeping the hood out of the horse's eye. They can be used as a layer under an existing sheet to keep the coat slick as well as flat. Lycra sheets can be used alone to protect the mane, tail or coat. Lycra material is generally moisture wicking to help keep your horse dry. Like new, only tried on my horse once but didn’t fit.
