Super strong, durable and resilient – yet slightly thinner and lighter -- butyl rubber replacement bladders come equipped in all TITLE Super Double End Bags, but are excellent replacements for all double end bags. Thinner and lighter craftsmanship help increase speed, rebounds and action, without sacrificing durability, longevity or quality. Exclusive rubber air nozzle has a locking lip that helps keep bladder intact at all times, even when the double end bag is deflated. Ideal for intermediate, advanced and elite double end bag training.

S fits sizes: 6” - 7” double end bags
M fits sizes: 7” - 8” double end bags
L fits sizes: 8" - 9" double end bags

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.
