High-density EVA foam is molded in sections rather than one flat sheet, which lets the protector flex with the torso during kicks instead of cracking at a single stress point — a common failure mode in cheaper single-piece designs.
Taekwondo and karate academies running point-sparring classes are the most common buyers, since the adjustable strap system needs to fit a wide age range from junior students to adult competitors within one production run.
Wipe the PU shell down after each session rather than machine washing it — the foam core can absorb water through stitched seams if fully submerged, which affects both weight and rebound over time.
