4kg (9lb) High Polish Atlas Competition Pro Kettlebell – Factory Second | Made in USA

The 4kg (9lb) High Polish Atlas Competition Pro Kettlebell – Factory Second delivers the same patented ergonomic design, lightweight aluminum construction, and Made-in-USA craftsmanship as our standard 4kg Atlas at a reduced price.

Designed for the full spectrum of kettlebell training, the 4kg Atlas supports strength, conditioning, mobility, balance, coordination, technique development, and skill progression across Pro Kettlebell’s 365-exercise library.

Factory Second: This kettlebell is fully functional and structurally sound but may have cosmetic imperfections such as polishing variations, surface marks, finish inconsistencies, or other minor manufacturing imperfections. Factory Seconds may also fall outside our tighter standard weight tolerance, but are never more than 2% off the marked weight.

High Polish Finish

Our High Polish finish celebrates the natural character of American-made metal rather than covering it with paint. Each kettlebell is polished to reveal unique grind marks, contours, and subtle surface variations before being sealed beneath a durable high-gloss clear coat.

Because this is a Factory Second, the finish may show more visible variation than our standard High Polish kettlebells. These cosmetic differences do not affect its intended training performance.

Patented Atlas Ergonomics

The Atlas features Pro Kettlebell’s patented ergonomic design in a compact, highly maneuverable profile. Its contoured arm rests are designed to position the kettlebell comfortably against the forearm, while the compact body helps keep the load close to the body during rack, overhead, and transitional movements.

The 4kg Atlas is made from aluminum to achieve the lighter weight while maintaining the familiar Atlas shape and training geometry.

A 33mm performance handle provides a comfortable grip for smaller hands and technical training. The wide handle window supports both one- and two-handed movements, while the flat face, extra-wide base, and grippable base rim expand the ways the kettlebell can be used throughout training.

A steel plate inside makes the 4kg Atlas compatible with Pro Kettlebell Magnetic Chip Weights, allowing you to make smaller, more precise increases in training load.
