This pack of three holds is in the shape of balls. The balls have a flat bottom to ensure a secure attachment to the wall. You can read the below bullet points for their dimensions.
This shape of hold is more fun than anything else. You can pinch or claw-grip them. You can even wrap the balls with your pinky finger against the wall. The balls do offer a very recognizable shape, and they are comfortable.
Creating full routes of BALLS with PROTONS makes for a unique style of a route that is both fun and engaging for the climber.
This set is a challenging yet appropriate difficulty for the beginner on a vertical wall. They will feel in the V1 grade range. They feel V3/4 on a 45-degree wall.
