FRESH NEW LOOK: Featuring our color and weight communication system, our Premium Kettlebell Prime creates a high-end look while keeping workouts straight forward. Same great design as our best-selling Premium Kettlebells, the Prime has a smooth vinyl covering to dampen noise, protect floors and guide users to quickly select the correct weight. Thirteen weights available. Kettlebells and handle sizes increase with the weight of the kettlebell - handles are 1 to 1 3/8" in circumference. Indoor use only. Racks available.
