Durable and sensitive crack gloves



Constructed from a single piece of thin Italian suede, the HAND JAM molds to your hands forming a perfect fit and provides uncompromised balance between protection, breathability, friction, and warmth. 

The HAND JAM is for all day wear, it provides protection when jamming and offwidthing, and is unobtrusive when face climbing or mixing free with aid.

We selected a high grade Italian suede, similar to that used on the best climbing shoes. It is durable and comfortable.

The perimeter of the HAND JAM is reinforced with a high strength laminate to ensure that the wrist strap and finger holes do not fail.

The thin leather allows you to feel the rock and climb with confidence while being protected from abrasion. This is essential when climbing many crack pitches or multiple days in a row.

All day comfort


A day of alpine climbing is long and likely involves both crack and face climbing. The HAND JAM is patterned to be fitted on your hand when jamming yet relaxed when face climbing and at belays – staying comfortable at all times so you can keep them on all day.

Thin and breathable

By forgoing rubber, the G7 HAND JAM is breathable and low-profile, keeping thin hands — thin hands.



Made from a single piece of leather, the suede strikes the ideal balance between breathability and warmth. Allowing the G7 HAND JAM to work on cold alpine climbs through hot days in the Creek.

Wide wrist strap


The wide strap sits comfortably below the crease on your wrist — allowing movement, distributing the load, and providing protection for deeper jams.



The hook and loop closure makes the G7 HAND JAM quick and easy to put on and adjust.

Like a pair of climbing shoes, the leather will stretch and mold to your hand — becoming uniquely yours.



The leather is durable and provides protection from abrasion, while remaining thin so you can feel your jams. It has the perfect amount of friction — most comparable to tape.

To provide the best fit, the HAND JAM is available in 5 sizes — each in a unique colour.

Measure: Palm circumference — just below the knuckles, hand should be relaxed.

Fit: Secure when hand is closed jamming, relaxed when hand is open.

Stretch: The leather will soften and mold to your hand like a new pair of climbing shoes — becoming uniquely yours.
