Our Take
The Onnit Primal Bell Howler is an 18kg cast-iron kettlebell moulded into the form of a snarling gorilla head. It's aimed at lifters who want functional training equipment with a striking visual identity — sitting firmly at the premium novelty end of the market rather than competing with commercial gym-grade workhorses on pure value.
Key Features
Cast-iron construction with a gorilla skull design, the handle forming the top of the head
18kg (approximately 40lb) weight, suiting intermediate kettlebell users
Textured handle surface intended to aid grip without chalk
Flat-bottomed base allowing stable floor storage and renegade row use
Single-piece casting — no welded seams between handle and bell body
Onnit's signature matte black finish with detailed facial sculpting on the body
Our Verdict
Worth considering for home gym owners who genuinely care about aesthetics and can absorb the premium price without wincing. If you're building a serious training setup on a budget, or plan to rack multiple bells for progressive loading, a conventional cast-iron kettlebell will serve you considerably better per pound spent.
