Top loaded and extra large, making it a snap to fill. The top flap will velcro shut so hay cant be drug out the top. Hay must be pulled from the webbed squares in front, so it can only come 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 and the bottom is mesh, allowing dust and dirt to fall through. TLHB24RB
