The 722 Slingshot is constructed of two layers of 1000D Nylon which balances durability with a shorter break-in period. The pocket remains open for fasteners and will not collapse when holding a tape measure or other tool. The rounded bottom allows for easy access to small tools and fasteners. The 722 attaches with a pair of clips and can be attached to a belt or another pouch. Attach them to the Ox or Mule for additional capacity.
