Derby Originals is the original inventor of the 4-sided hay bag, U.S. Patent No. D742,078. Our four-sided hay bags are the only bags on the market that allow your horse to freely eat from any part of the hay bag. These patented hay bags are the result of years of careful study and testing to create a design that is attractive, functional, durable, high-quality, and preferred by horses. Our bags are constructed of reinforced nylon webbing that is stronger and more durable than any mesh or fabric hay bag. These bags are designed with cross stitches at every intersection and bartack stitching at all stress points along the top, sides, and bottom of the bag. This hay bag also features our exclusive Super Tough Bottom: a grid of reinforced nylon webbing that will never rip like solid or mesh bottoms. Our bags are built tough from premium materials and are designed to last for years to come. This hay bag is designed to be a great everyday feeder for most horses and other animals: it measures 19x18x26 in. and can hold about 7-8 flakes of hay. This hay bag has 1.75 in. square openings which will prevent hay wastage and slow down their rate of consumption, but still allow for frustration-free feeding. This premium hay bag also includes a 1-year limited manufacturer's warranty offered by Derby Originals.

• HOLDS 7-8 FLAKES of HAY - this 19x18x26 in. hay bag with 1.75 in. square openings holds approx. 7-8 flakes of Timothy, Orchard, Alfalfa, or any other type of hay. Our hay bags were designed to minimize frustration and can be stuffed in seconds.
• EXCLUSIVE PATENTED 4-SIDED CONSTRUCTION - this hay bag features Derby Originals patented nylon web design that allows your horse to eat from any part of the hay bag. This design eliminates the risk of material rips and tears found in other hay bags.
