The RDX S4 boxing gloves are handmade with durable and authentic cowhide leather that will not batter easily. The cowhide outer is matched with a low-density membrane grid foam inner that densely pads the knuckles from the power of fist-meeting-face impact. The palm and wrists are protected with a thin but effective sheet of shock-absorbent gel that absorbs any excess force. The interior of the gloves is lined with antibacterial microfiber wicks that pulls the moisture away from the hands to keep them ventilated and cool. The new taka duo elastic hook-and-loop strap secures and supports the blows while keeping the wrist aligned with the hand for true-to-form punching stance. These gloves are also ideal for muay thai training and sparring with trainers and punching bags.
