Tough, super fast and lightweight leather build. All-leather welted seams, triple stitched and precision balanced for true rebounds. Loop is extra-reinforced for long wear. Complete with extended-life rubber bladder.
You MUST moisten the needle before inserting it in the bladder (Petroleum Jelly is best.) This will help prevent small tears in the inflation valve and deflation of your bag.
