The Universal Ground Blind Accessory bag attaches to all hub-style ground blinds in seconds. The two webbing straps wrap around the cross rails of the hub blind and attach with straps. The 8"x10" pleated bag is large enough to hold multiple calls, along with a folding saw, and snacks. The bag also has a 4.5"x5" front zipper pouch for mouth calls, hunting license or other small items. The front mesh pouch holds a slate call, striker, or grunt tube. Also attaches to all treestand shooting rails and some treestand seat brackets.
