Onyx Adjustable Soft Kettlebell - Water & Sand Fillable

Onyx Adjustable Soft Kettlebell 

One Kettlebell. Five Weight Options.

Fill With Water Or Sand. Adjust In Seconds.

Soft, Durable & Floor-Friendly.

The Onyx Adjustable Soft Kettlebell gives you a full range of kettlebell weights in one compact, space-saving design. Simply fill with water, sand, or a combination of both to dial in the exact resistance you need - no need for a whole rack of kettlebells.

Adjustable From 1kg Up To 12kg

Fill with water for a lighter range of 1-7kg, sand for up to 10kg, or combine both for a hybrid fill up to 12kg. That's one kettlebell covering the equivalent of a 5-piece set, perfect for progressive training as your strength improves.

Soft, Floor-Friendly Design

Unlike traditional cast iron or steel kettlebells, the Onyx features a durable soft-shell body (3-6mm thick, reinforced where it matters most) that's gentle on floors, safe around kids and pets, and won't damage equipment if dropped. No more loud clangs - ideal for home gyms, apartments, and studios.

Firm, Anti-Slip Handle

The 33mm diameter handle is fused seamlessly to the body and finished with an anti-slip texture for a secure grip through swings, cleans, presses, and squats - even when your hands get sweaty.

Specifications

Who It's For

Perfect for home gym owners, apartment dwellers, beginners, and anyone who wants the versatility of multiple kettlebell weights without the cost, noise, or floor damage of a full rack of cast iron kettlebells.

FAQs

What can I fill it with?
Water, sand, or a combination of both - water alone gives a lighter range, sand or a sand/water mix increases the maximum weight.

Is it safe for indoor floors?
Yes, the soft-shell body is gentle on floors and quiet if dropped, unlike traditional cast iron kettlebells.

Will the handle bend or feel uncomfortable?
No, the handle is firm with a slight give for comfort and features an anti-slip texture for secure grip during intense sessions.

Is a funnel included?
A funnel is recommended for filling but is not included - any standard kitchen or garden funnel will work.
