The next generation of crack gloves, offering superior hand and finger protection and a high performance factor. Our super Crack Gloves feature a thicker layer of super sticky texture Climb X climbing rubber, extending all the way down to the first joint for those especially gnarly off widths. The super Crack Glove's open palm design and flexible material still allow plenty of ventilation while conforming to the shape of your hand, offering the best comfort with superior climbing ability. Measurment is approximate and is taken from the outside of the back of the hand, to the outside of the first knuckle of the index finger. Small: 3.5 in (9cm) Medium: 3.75 in (9.5cm) Large: 4.25 in (11cm) X-Large: 4.5 in (11.5)
