This Deluxe Top Load Hay Bag is extra large making it very easy to fill. It features a top flap that velcros shut so hay can't be drug out of the top. It also features a long adjustable strap with snaps making it easy to hang almost anywhere. The may must be pulled from the webbed squares in front which lessens waste. The front and back are made of tough poly for durability and the bottom is mesh allowing dust and dirt to fall through.
