The JAMROCK gloves have been specially designed for crack climbing. The tried-and-test RX-1 ALLROUND rubber (1 mm) on the outside provides extra grip while also protecting the back of the hands against injuries when jamming them into cracks. The inner lining is made from durable microfiber covered in a silicone print to optimize the adhesion between the gloves and the back of the hands.

Inside or Outside
Crack gloves close around the wrist typically with a velcro-like strap which lays either on the inside of the wrist (the palm side) or the outside of the wrist (the back of the hand). Most gloves close on the inside of the wrist where the closure is more protected from coming undone while jamming, though some manufacturers choose to close on the back for a lower profile closure that is more comfortable against the softer inner arm.
Crack gloves are made with different types of cracks and rock in mind. Some manufacturers have begun building greater thumb protection into their designs which can be beneficial if you are climbing wider cracks where fist-jamming is common. We consider thumb coverage to completely cover the knuckle and at least part of the first digit of the thumb. If only part of the knuckle is covered it is considered partial.

Strap coverage refers to the wrist closure strap having a built-in place to stow once it is closed. This feature is included on some gloves to help avoid the strap being opened when you don’t want it to be.

Tend to fit average to small. Tough to fit accurately with a single measurement. All sizes overlap greatly, so you may find your measurement fits in as many as three sizes.
If you fit multiple sizes, we recommend choosing the larger if you can't try them on first.
This refers to the material or materials that make up the main body of a crack glove. This is usually either a form of natural or synthetic suede, synthetic material or combination of both. This may include the materials used to make holes or loops for fingers but should not be confused with the Backing material that is added on the back of the glove for contact with the rock.
This is the material that crack glove manufacturers adhere to the back of the glove to add friction and padding between your hand and the rock. This is usually some form of rubber or synthetic rubber compound and can be in very thin to relatively thick, although not all crack gloves have backing material.

|Performed well on parallel cracks and thin splitters, especially when undersized. Can provide extra fill for thin hands when worn oversized without feeling too slippery against the hand. The most padding out of the thin gloves we've tested makes them great to have when hand cracks get irregular. But the very thin suede adds almost no structure to the glove making flaring jams feel less secure than a more robust glove. Decent grip on slippery cracks thanks to thicker rubber and thin, flexible suede. Still not enough padding on very sharp edges or features inside cracks to feel great.
When comparing to all other gloves on the the thin/flexible side of the market, the Jamrock definitely stands out as a chunkier, more padded and stiffer glove. They’re tough to size correctly, though sizing down a bit hasn’t produced too many issues for our testers. Durability of the finger loops is a bit of a question mark, though we haven’t personally witnessed any blowouts, so those expecting to really wrench and abuse a pair of crack gloves should be wary. Overall we’ve found them to be a comfortable wearing glove that adds a bit of extra padding for their weight class, and sticks to the hand a bit closer to tape than any suede glove we’ve tried.
