Black Diamonds Crack Gloves deliver the comfort, performance, and protection you need on those mega crack climbs. Constructed from synthetic suede, using 3D patterning, they provide a superior fit for lasting comfort. The suede achieves a precise balance between abrasion resistance and breathability and is white to reduce heat uptake when youre climbing in full sun. For grip on the back of the hands, BD used a 0.6mm rubber adhesive film. Set into a moulded depression, it transitions seamlessly between the rubber and suede; maintaining thinness it keeps the glove supple and dextrous.
