What is Membrane Grid padding in boxing gloves?

Membrane Grid padding is RDX's multi-layer foam system that uses alternating density layers to manage impact in two stages: the outer layers absorb and slow the initial force, while the inner layers provide a firmer base that prevents full compression (known as "bottoming out"). Five-layer systems like this distribute impact energy across more material than a single-foam design, reducing peak stress on the knuckles during heavy bag rounds.

What are 4oz bag gloves best used for?

4oz bag gloves are designed for solo training drills — heavy bag, speed bag, and pad work. At 4oz, they're lightweight enough to develop hand speed and combination fluency but should never be used for partner sparring. Use heavier gloves (10oz+) for coach-held pad work and 14oz+ for sparring.

Do I need hand wraps with 4oz bag gloves?

Yes — always wrap your hands before putting on bag gloves. Even at 4oz, repeated strikes generate cumulative stress on the small bones of the hand and wrist. Hand wraps distribute that load, stabilise the wrist, and protect the knuckle skin. Cotton or gel wraps both work well under bag gloves.

How do I choose the right colourway?

The F6 Kara Bag Gloves are available in Black, White, Gold, Red, and Pink — all in the same 4oz specification. Colourway choice is purely aesthetic. If you're training at a gym that uses colour-coded equipment, choose a colourway that doesn't conflict with your gym's system. All colourways share identical padding, leather, and closure construction.
