RDX Unfilled Kettlebells — Adjustable Weight, Portable Home Gym
The RDX Unfilled Kettlebells are a smart, portable alternative to traditional cast iron kettlebells — designed for home gym use where space and transport matter. Fill with sand or pea gravel to your target weight, and adjust as you progress — giving you a fully customisable kettlebell that travels anywhere without the weight penalty of solid iron.
Construction & Materials
Crafted from anti-rip Cordura fabric — the same high-durability material used in tactical equipment and premium gym bags — making these significantly more durable than standard fabric training tools. The flat-bottomed design prevents rolling during exercises and between sets, and allows stable floor storage. The PVC-reinforced textured handle provides a firm, non-slip grip during swings, cleans, presses, and deadlifts — essential for the explosive movements where kettlebell grip matters most.
Filling & Weight Adjustment
Triple hook-and-loop reinforced filling sleeve makes filling and weight adjustment straightforward — open, fill to your target weight, seal securely. Fills with fine sand, pea gravel, or rubber pellets. Weight guide: 4kg for beginners, 6kg for intermediate, 8–10kg for professional level. Reinforced stitching at all stress points ensures the bag holds its weight and shape through intense workouts without leaking or splitting.
Training Applications
Suitable for kettlebell swings, goblet squats, cleans, presses, Turkish get-ups, and all standard kettlebell movements. The compact, portable design makes these ideal for home gyms, travel training, and outdoor sessions. Pairs well with our resistance bands and RDX weighted sandbag for a complete functional training setup.
