These competition TOP TEN gloves are made of 100% high quality and extremely robust Nubuk II synthetic leather. The cut and fit are especially suited for narrower hands. The one-piece foam padding made of PPS is anatomically preformed and inserted into the hand-stitched synthetic leather cover – saving you strength and energy and avoiding muscle strain as your hand is guided into the ideal stroke position. Additional features include robust artificial leather, timeless and sporty design, and perforated palm. World Association of Kickboxing Organizations approved.
