"STIFFY" Back Plate Kettlebell program grip enduranceYou asked, and we delivered. Some of our customers recommended an upgrade option for the backplate of the kettlebell backpack to provide a "stiffer" backside of the backpack. So we did it. Our backpacks already come with their standard backplates like always, but they are definitely flimsier in comparison to the "STIFFY." At 3 16" thick and barely bendable, this backplate provides a substantial improvement in the "stiffness" of the backpack's backside.
