Warrior Fitness is now offering 55 LB sacks of crumb rubber in 1mm to 3mm granules. This quality fill material—an industry standard—is suitable for use with a wide range of products. For small garage gyms and larger training facilities, alike, buying fill materials in bulk can offer much greater preparedness and flexibility when setting up or customizing sandbags, loadable mallets, etc.

Crumb rubber is sourced directly from recycled tires and is highly durable while also enabling precise measurements. The weight tolerance on each of these bulk sacks is +/- 1 LB.
