The Portabrace SP-SET Sack Pack is a heavy duty, sack-style carrying bag for carrying all sorts of grip and field-production gear. The bag is constructed using military-grade, 1000-denier Cordura Nylon material. The Cordura is tear-resistant and has an extra layer of water-poof coating added. The bag opens wide at the top and is as simple to use as a shopping bag but with all the extra advantages of a well constructed Porta-Brace® case. The bag has two slip pockets, one on the front and one on the back. There is an extra layer of padding on the bottom of the case to help protect the contents of the bag and to help stabilize the bag when placed on the ground. The wide-mouth opening cinches at the top for secure transport. The bag has a strong nylon-web handle set with comfortable suede-leather handle grips. The SP-SET field bundle comes complete with a small, medium, and large size Sack Pack.
