This large slow feed hay net holds up to a half bale of hay (standard 2-string bale) to keep your horse busy at home, at the show or at the campground. It is made of durable poly cord that is tightly knotted to prevent stretching. The 1 1/2" x 1 1/2" openings slow down consumption for a healthier and more natural feeding experience while also helping to reduces hay waste.40" long, 1 1/2" x 1 1/2" openings
