Overview
The SandBells® by Hyperwear are a versatile, neoprene-based weight training tool that bridges the gap between dumbbells, kettlebells, and medicine balls. Unlike rigid weights, these disc-shaped, sand-filled "bells" provide an active, shifting load that forces the user to engage more stabilizer muscles and grip strength. Because they are soft and forgiving, they are exceptionally safe for all ages and training environments, from high-performance athletic facilities to home living rooms.

Key Features and Specifications
Material: High-quality black neoprene construction for a soft, durable, and comfortable grip.
Design: Unique, patented disc shape without a traditional handle, specifically designed to challenge the grip, wrist, and forearm.
Internal Filling: Ships pre-filled with clean, dust-free sand sourced sustainably in the USA.
Active Weight: The shifting sand inside creates a "live" weight that moves during exercise, increasing the difficulty of stabilization.
Weight Range: Available in a wide variety of color-coded sizes ranging from 2 lbs to 50 lbs.
Safety: The soft exterior makes them safe for all flooring surfaces (indoor and outdoor) and reduces the risk of injury if dropped.
Performance Benefits
Grip Strength Development: The lack of a handle forces the user to pinch and grasp the neoprene, significantly improving hand and forearm strength.
Dynamic Stability: The shifting nature of the sand requires constant muscular adjustment, activating secondary stabilizers that traditional weights often miss.
Explosive Movements: Ideally suited for high-intensity power movements, including slams, tosses, and throws, as the sand dissipates energy upon impact rather than bouncing.
Hybrid Functionality: Can be used for traditional strength exercises (like cleans and curls) or integrated into conditioning circuits, yoga, and rucking.
Maintenance and Care
Cleaning: To clean the neoprene exterior, wipe down with a damp cloth and mild soap. Do not submerge in water or use harsh chemical cleaners which can degrade the neoprene fibers.
Surface Usage: While durable for outdoor use, avoid using SandBells on highly abrasive surfaces like jagged concrete or asphalt for extended periods to prevent premature wear of the neoprene shell.
Impact Awareness: While designed for slams, avoid striking the SandBell against sharp objects or corners that could puncture the fabric and cause sand leakage.
Storage: Store in a dry environment. If the SandBell becomes damp from sweat or outdoor use, allow it to air dry completely before stacking or storing to prevent mildew.
Warranty Information
SandBells are generally backed by a 1-year limited warranty (and up to 2 years through the manufacturer, Hyperwear) covering defects in materials and workmanship under normal use. The warranty does not cover damage resulting from accidental punctures by sharp objects, use on highly abrasive surfaces, or "slamming" beyond the intended design limits.
Frequently Asked Questions
Q: Do these come empty or pre-filled? A: Unlike many sandbag products, Rogue ships SandBells pre-filled and ready to use immediately out of the box.
Q: Can I use SandBells on my hardwood floors? A: Yes. The soft neoprene exterior is one of the safest options for home gyms, as it will not scuff, dent, or damage most flooring types when dropped.
Q: How do I tell the weights apart if they are all black? A: While the main body is black, each SandBell features a color-coded outer trim and a printed weight label for easy identification during fast-paced workouts.
Q: What is the difference between a SandBell and a SteelBell? A: The SteelBell uses steel shot as a filler, making it much denser (smaller in size for the same weight) and creating a more aggressive, water-like shifting effect compared to the sand-filled SandBell.
