How does a nylon weightlifting belt differ from a leather belt?

Nylon belts are lighter, more flexible, and easier to clean than leather belts. They compress more than leather under load, which some lifters find more comfortable during dynamic movements like power cleans and Romanian deadlifts. Leather belts are stiffer and provide a more rigid brace for maximum-effort squats and deadlifts at the highest loads. The RDX RX1 nylon belt is suited for general training, high-repetition work, and exercises requiring a range of hip and torso movement — areas where a stiff leather belt would feel restrictive.

What is the Anti-Open Closure system?

The Anti-Open Closure mechanism is a secondary locking feature on the RX1 buckle that prevents the closure from releasing under tension during a lift. It adds an additional engagement point that locks the buckle in place regardless of the direction of force applied — particularly important during heavy squats and deadlifts where abdominal pressure pushes outward against the belt throughout the movement.

How do I select the right size?

Measure around your waist at the navel. The belt should fit snugly with the Hook and Loop closure engaging across the middle of its adjustment range — if the closure is at its tightest position, size down; if at its loosest, size up. Available in S, M, L, and XL. The 3-inch velcro strap provides additional fine adjustment within each size, giving a more precise fit than fixed-hole belts.

How do I clean a nylon gym belt?

Nylon gym belts can be spot-cleaned with a damp cloth and mild soap, then air-dried. For a deeper clean, hand-wash in cool water with mild detergent and hang to air-dry fully. Do not machine wash on hot cycles or tumble dry, as heat can shrink the nylon and degrade the Hook and Loop fastener over time. Allow the belt to dry completely before storing or reusing to prevent odour build-up.
