200 grams of poly fill inside this Arktis Neck Cover make it an ideal companion for the Arktis Regular Neck Midweight Turnout. It's designed to work exclusively with the Arktis Turnouts. The 1200 denier polyester outer is waterproof and breathable and is fully lined with smooth poly taffeta. The neck cover closes securely under your horse's neck with two hook and loop straps that pass through stainless steel D rings. A gap-free and comfortable attachment to our Arktis regular neck turnouts (sold separately) is accomplished thanks to two hook and loop strips that fit directly into the opposite hook and loop strips on each of the turnout blanket s shoulders. Since it has no metal components for attachment to the Arktis Turnout, it's more comfortable for the horse, no snaps to pinch and poke her, especially while laying down.
