Derby Originals Supreme 4-Sided Slow Feed Hay Bag - Durable Slow

Our review of the Derby Originals Supreme 4-Sided Slow Feed Hay Bag finds it best for horse owners who need a rugged, slow-feeding solution that holds large flakes and stands up to regular use. The single biggest reason to buy is its patented 4-sided nylon web construction that lets horses graze from any side and resists the rips and tears common to mesh bags, making it a practical choice for barns that want to reduce waste and encourage natural grazing behavior.

Key Features

• 4-sided patented design: The unique nylon web construction allows a horse to eat from any part of the bag, reducing fighting over openings and uneven wear.
• Holds 2-3 flakes: At 22x8x25 in with 3.5x1.75 in rectangular openings, it accommodates 2-3 flakes of Timothy, Orchard, Alfalfa or similar hay for longer grazing sessions.
• Super Tough Bottom: Reinforced overlapping nylon webbing on the bottom keeps the bag durable, lets dust and debris fall away, and maintains hay freshness.
• Heavy-duty construction: Cross stitches at intersections and bartack stitching at stress points create a strong, long-lasting bag preferred in active stables.
• Improves digestion: Slow feeding mimics natural grazing, which veterinarians recommend to reduce ulcers, colic risk, and boredom-related vices.
• One-year warranty: A limited 1-year manufacturer warranty covers defects in materials and workmanship for added buyer protection.

Who It's For

This hay bag is aimed at horse, mule, and donkey owners who want to reduce hay waste and encourage natural grazing rhythms. It suits stalls, trailers, and paddocks where a robust, easy-to-fill bag is needed and where animals may be rough with feeding equipment.

Owners seeking a very lightweight or ultra-compact feeder, or those who prefer soft mesh that shows the hay through the fabric, may want to look elsewhere. Also, if you require a feeder with extremely small feed openings for pellets or chopped forage, this design is optimized for standard hay flakes.

Pros & Cons

Pros

• Durable nylon webbing and reinforced stitching resist tears and handle heavy use well.
• Spacious size and 3.5x1.75 in openings let horses access hay slowly while holding 2-3 flakes.
• Super Tough Bottom design helps keep hay fresh and sheds dust and debris.
• Helps replicate natural grazing, which supports digestion and reduces boredom-related behavior.

Cons

• The velcro closure has mixed feedback from customers and may be less preferred by some users.
• Not intended for very fine or chopped feeds that require smaller openings.
