Rubber Coated Kettlebell

Price varies
Gravity CastPowder CoatedFloor Protection

While gravity casting ensures solid structural integrity, the inclusion of a rubber coating is a research-identified red flag as it can trap moisture and hide casting imperfections. It lacks the explicit CNC-machined flat base and +/- 1% weight tolerance specs found in gold-standard professional bells.
