Derby Originals Superior 4-Sided Slow Feeder is a horse hay bag designed to slow hay consumption and reduce waste, with 1.75-inch (4.445 cm) square openings and room for about 2–3 flakes.

• Patented four-sided design — lets a horse reach hay from any part of the bag.
• 1.75-inch (4.445 cm) square openings — restrict hay access while allowing horses to feed.
• 22 × 8 × 25 inches (55.9 × 20.3 × 63.5 cm) — holds about 2–3 flakes for everyday feeding.
• Reinforced nylon webbing with a Super Tough Bottom — built with cross-stitching and bartack stitching at stress points.
• One-year limited manufacturer’s warranty — covers manufacturing defects.

For horses that eat hay quickly, a slow feeder can help make hay available in a more controlled way and reduce loose hay waste. This bag is designed for everyday feeding for most horses and other animals, with a layout that provides access around the bag rather than from just one face. Its size suits a small hay ration of about 2–3 flakes.

How does the four-sided design change access to hay?

The patented four-sided construction lets a horse eat from any part of the hay bag. Derby Originals holds U.S. Patent No. D742,078 for its design, which offers access around the bag instead of limiting feeding to a single side. The configuration was developed through years of study and testing.

• The design is intended to allow feeding from any part of the bag.
• It is designed for horses and other animals as an everyday feeder.

How much hay does the bag hold, and what size is it?

The bag measures 22 × 8 × 25 inches (55.9 × 20.3 × 63.5 cm) and holds approximately 2–3 flakes. It can be filled with Timothy, Orchard, Alfalfa, or other types of hay, and is designed to be stuffed in seconds. Compare the dimensions with your intended feeding area when choosing where to use it.

• Capacity is approximate and depends on the hay flakes.
• Made for a small everyday hay ration rather than a large bale.

Do the openings slow feeding without blocking access?

Yes. The 1.75-inch square openings limit how quickly hay can be pulled out while still allowing access for feeding. Slow feeding is intended to help replicate a horse’s natural grazing pattern; horses are designed to spend up to 18 hours a day grazing. The feature description also notes that slow feeding is recommended by veterinarians to help prevent gastric ulcers, colic, and boredom-related behavioral vices.

• The openings are square.
• The restricted access is designed to reduce hay wastage and slow consumption.

What materials, bottom construction, and warranty does it have?

Reinforced nylon webbing forms the bag, with cross stitches at each intersection and bartack stitching at stress points along the top, sides, and bottom. The webbing construction is stronger and more durable than mesh or fabric hay-bag materials. Its Super Tough Bottom uses overlapping nylon webbing in a grid, rather than a solid or mesh base; the design lets dust and debris exit while helping keep hay fresh. Super Tough Bottom is a registered trademark, No. 6259398.

• The bottom is designed to resist the tearing associated with solid or mesh bottoms.
• The one-year limited manufacturer’s warranty covers manufacturing defects, not accidental damage or wear and tear.

This feeder suits horse owners who want a compact hay ration, slower access, and feeding access around the bag for everyday use. It is sized for approximately 2–3 flakes, with reinforced nylon webbing and a patented four-sided layout at its core.
