This top loaded, extra large hay bag from Jeffer’s Equine is a snap to fill. The top flap has hook and loop closure so hay can’t be pulled out of the top. Hay is only pulled from the webbed squares in front so it comes out in small amounts, which lessens waste. Long adjustable strap with a snap makes it easy to hang almost anywhere. Front and back are made of tough poly for durability. The bottom is mesh allowing dust and dirt to fall through.
