Supreme Products Waterproof Tail Bag - Black. The Supreme Products Waterproof Tail Bag is an equine wardrobe essential for keeping your horse's tail clean and beautiful. The waterproof tail bag is a must-have for show days and travel, but it can also be used in the stable and field all year to keep the hair in good condition and prevent discoloration in white tails. The waterproof tail bag is designed with practicality in mind, allowing for the addition of a bandage/tail guard if necessary, and has an elasticated draw top to keep the bag securely in place while also acting as a barrier, keeping mud, bedding, and anything else from dirtying the tail! The bag has a loop for threading a plaited tail through for further security, a full-length opening for easy application to a thick tail, and a touch tape closure option on the bottom of the bag that allows you to fold the tail bag in half.
