Derby Originals' line of slow feed hay bags has been meticulously designed, tested, and improved over the past 15 years in order to give you a product superior to anything else available on the market. Our unique web front hay 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 21x7x25 in. and can hold about 2-3 flakes of hay. This hay bag has 1.75 in. sq. front 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 6-month limited manufacturer's warranty offered by Derby Originals.
