Spirit Combat Sports - Heavy Bag PRO Filler 100LB

Looking to fill an unfilled heavy bag shell or bring new life to an old, sagging bag?

VenomBoxing Heavy Bag Fiber Filler (40 lbs) is the same premium-grade material used inside the official UFC heavy bags we manufacture.
While the filler itself is not a UFC-branded product, it’s made to the same professional training standards — ensuring top-tier density, rebound, and durability for every strike.
