Stow a half bale of hay and keep things neat and tidy when you're on the go. Tough, water-resistant 600 denier nylon protects hay from the lelemnets and will hold up over time. These bags are a must have if you are hauling horses anywhere. They come in so handy. Stainless steel grommets provide air holes to allow moisture to escape, keeping the hay fresh. Zips on three sides for effortless loading and unloading. Padded shoulder strap and carrying handles make it a cinch to tote.
