Master Jam Crack Gloves

The New Standard in Crack Performance. Re-engineered with a thinner profile, stickier rubber, and a more ergonomic fit. These gloves have been used to climb some of the world’s hardest cracks, so get ready to protect your skin, maximize your dexterity, and jam harder than ever before

The Master Jam Crack Glove isn’t just an update, it’s a total overhaul. The WideBoyz have taken years of feedback to create a glove that feels like a second skin while still providing that “bomber” protection.

Advanced rubber & dexterity: Using a new, stickier rubber compound and strategically reduced the thickness in non-essential areas. By mixing in a high-friction, thinner material, they've kept the glove incredibly dexterous on the hand. The result? A glove that jams into more difficult cracks with ease, without sacrificing grip or protection.

Ergonomic fit: The Master Jam features a completely redesigned shape that follows the natural contours of your hand. It moves with your hand when transitioning through different jamming techniques.

Enhanced comfort on finger and thumb loops:  Keeping the signature finger-loop construction but increased the width of the loops to eliminate pinching on long sessions. The fit of the thumb loop has also been refined whilst still providing vital protection and friction for fist, teacup and stacked jams

Built to Last: Durability is key when you’re grinding against granite. They've strengthened the eyelet, improved the rubber-to-material bonding and eliminated the stitching so that there are less wear points. 

Face Climbing Ready: The palm remains free, and we’ve kept the material between the fingers to an absolute minimum. This ensures you have normal hand-to-rock friction on face holds and prevents that “baggy” feeling when you’re out of the crack.
