If you are looking for triple protection for you Horse Trailer, the Beverly Bay Trailer Cover is the cover you are looking for. Triple-Layer top panel with polypropylene side panels provide maximum protection for your bumper-pull Horse Trailer. On the other hand, it's a fully breathable fabric, which allows trapped moisture to evaporate from within, so your trailer can be extra protected. Passenger-side zipper entry doors allow access during storage. Heavily reinforced rear corners resist tears and snags. Highly U.V. resistant and almost waterproof. Elasticized bottom hems at front and back provide a snug fit. Bunny-ear cinching system contains excess fabric. Strap and buckle secures cover firmly in place underneath trailer. Will work for all Thoroughbred/Standard bumper-pull trailers between 8 and 18 feet long. Cinching system accounts for whether the trailer has a round front or a "v" front. Exclude hitch when determining trailer length.
