Harbinger Pro Wristwrap Weightlifting Gloves with Vented Cushioned Leather Palm Patented WristWrap design is the most powerful wrist support system ever built into a glove. Heavy duty stretch panels between fingers and across back of hand enhance ventilation, flexibility, comfort and fit. Double leather palm and fingers surround a layer of resilient foam to protect hands against abrasion. Reversed top grain leather on palm maximizes abrasion resistance without compromising tear strength. Wrap around thumb protection cushions and covers the inside of the thumb with a second layer of leather to protect against abrasion.
