Key takeaways
- A pocket is a hole/depression that fits one to a few fingers, not the whole hand.
- You grip it by inserting the fingers that fit and pulling.
- Pockets concentrate load on fewer fingers, making them strenuous and injury-prone.
- Single-finger 'monos' are especially hard on the fingers — warm up and use them cautiously.
What a pocket is
A pocket is a climbing hold consisting of a hole or depression — in the rock or a molded gym hold — that accepts one, two, or three fingers rather than the whole hand. You grip it by inserting the fingers that fit and pulling. Pockets are common on certain rock types, notably limestone.
How to grip one
Insert the strongest fingers that fit (often the middle two for a two-finger pocket) and pull, using a crimped or open-hand position depending on the pocket. Since only some fingers are in contact, good body position and footwork to reduce the load matter, as does choosing which fingers to use.
On a limestone route, a climber reaches a two-finger pocket, slots their middle and ring fingers in, and pulls — keeping their feet high to take weight off those two fingers — rather than yanking hard and risking a tweak.
Finger safety
Pockets concentrate body weight on just a few fingers, stressing the tendons and pulleys — and single-finger ‘monos’ are the most extreme, carrying real injury risk. Warm up thoroughly, build finger strength gradually (e.g., via hangboard work), and use pockets cautiously, just as with hard crimping and small edges.
The bottom line
A pocket is a climbing hold that's a finger-hole — fitting one to a few fingers rather than the whole hand. Gripping one concentrates load on those fingers, making pockets strenuous and, especially as single-finger 'monos', a real finger-injury risk. Use the strongest fingers that fit, support with good footwork, warm up well, and treat monos with caution.
Frequently asked questions
What is a pocket in climbing?
A pocket is a climbing hold that's a hole or depression — in the rock or a molded gym hold — which fits only one, two, or three fingers rather than your whole hand. You grip it by inserting the fingers that fit and pulling on it. Pockets are common on certain rock types, notably limestone.
How do you grip a pocket?
Insert the strongest fingers that fit (often the middle two for a two-finger pocket) and pull, using a crimped or open-hand position depending on the pocket and your strength. Because only some of your fingers are in contact, the load concentrates on those fingers and their tendons, so good body position and footwork to reduce the load matter, as does choosing which fingers to use.
Why are pockets (especially monos) hard on the fingers?
Because they concentrate your body weight on just one to three fingers instead of spreading it across the whole hand, putting high stress on those fingers' tendons and pulleys. Single-finger pockets ('monos') are the most extreme, loading one finger heavily, and carry a significant risk of finger injury. Warming up thoroughly, building finger strength gradually, and using pockets cautiously help reduce the risk.
