The dome shape of these slopers offers a unique grip as compared to a traditional sloper. Due to the curvature of the shape, your thumb and pinky can engage on the climbing hold. The dome is a staple shape for climbing walls. No matter what level of climber you are, beginner to expert, your wall will find a use for a dome. It might be a giant foothold for the beginner or a crazy hard sloper on a 20-degree overhanging wall. Get some!
