GRANITE GEAR Staff Bag Staff sack with an oval bottom for easy packing. Made of silnylon, which is smooth and makes it easy to put in and take out your belongings. Unlike typical staff bags, the construction is very good and durable. Please check the images for details. If you have any questions, I will add more images, so please ask in the comments section. I will fold it up small for shipping, so please purchase if you understand.
