SCYntz’s revolutionary Extoprene striking zone strip adds to the experience of the speed bag by adding more bounce, speed and momentum to your pace. The bottom patch and Exroprene striking zone are at the widest portion of the bag so that you get just the right amount of weight propelling the bag through a perfect range of motion. The SCYntz Speed Bag is constructed from genuine leather with impressive double-stitched, welted seams for durability and shape retention. Available in Small (5″x8″) and Medium (6″x9″).
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.
