Purple 15lb Mikolo kettlebell with a black handle, surrounded by blue and black kettlebells

Solid One-Piece Cast Iron Core

Built from a single solid mold, each Mikolo Kettlebell eliminates the need for welding or assembly seams—creating a perfectly balanced, ultra-durable body that stands up to years of heavy training.
Unlike hollow or jointed designs that loosen or crack over time, this one-piece construction provides rock-solid stability, smooth handling, and consistent performance with every swing, press, or clean.

FEATURES

Extra-Wide Handle with Premium Coating

The wide matte-finished handle provides a secure, non-slip hold for both single- and double-handed movements. The premium coating enhances grip comfort and reduces wrist fatigue during dynamic workouts.

Color-Coded Weights

Every Kettlebell features a distinct color for quick identification. The weight marking and logo are seamlessly printed (not raised), so they won’t scratch your hands or distract your grip during training.

Stable Flat Base

Designed with a wider, flat bottom for better stability during storage and floor-based exercises such as renegade rows or push-ups.

Soft Neoprene Shell

A durable neoprene layer wraps the kettlebell body to protect your floors, prevent slipping, and feel soft on your palms. The ergonomic curve of the bell makes it easier to hold close to your body during lifts.

The kettlebells arrived quickly. They were packaged well. They are very attractive and well made. Exactly as advertised. This was a great purchase and I am so glad I did!

Exactly what I thought I was getting. I like the coating on them. The arrived quickly. The only issue is the 20lb bell’s handle is very rough.

This thing is so freakin adorable. I only have 35lb and 25lb kettle bells and this just looks so funny next to them. But it's really perfect for doing windmills and other light mobility work. Also sweet that is has the neoprene coating because my toddler has already dropped it on the floor more than once and it was relatively quiet and didn't chip or cause any issues.

Best Investment for a Beginner! I was overwhelmed where to start with kettlebells. This 3-weight set took the guesswork out. I began with the 5LB to learn the movements without hurting myself, and having the heavier ones right there motivates me to keep going. The handles are comfortable and the colors make it easy to grab the right weight.

Excellent form, grip size & texture, and weight distribution. For a couple of decades I've had six pairs (each pair of increasing weight) of Dragon Door kettlebells --what may be the first and arguably the gold standard for North American kettlebells. A few years ago, a house sitter stole the smallest set--and given their small weight, I wasn't all that motivated to replace them. At least not until a 5lb kettlebell became available via the Vine program. It actually looked better than the original Dragon Door in this size, being more like the larger sizes of Dragon Door (the two smallest DD sizes were done differently, with urethane coating and smooth handles). Having already another Mikolo item (their six pound medicine ball) with which I am extremely pleased, I ordered up this new kettlebell, and like their medicine ball, it has exceeded my expectations for it. Consistent with the product description, this kettlebell is of solid cast iron, with a neoprene coating over the bottom two thirds. I like this one so much that I have ordered a second at full price (I prefer doing most exercises with one in each hand). Yes it is light weight, but not all lifting is purely for attaining maximal size and weight. It makes for an excellent warm up before heavier lifting, and it excels at rehabilitation where movement is as important as weight. Unlike most weight training equipment, this one can be blend into its surroundings, making storage uncomplicated.
