Route setters really like holds that offer a variety of grips, using them with delight to create brain-teasers for climbers. Grip our Boulder Pure Eggs Mini Volumes 5 (PU) with an open hand, as a sloper, or as a pinch. Polyurethane means a lightweight yet very solid hold. This hold works extremely well for setting overhanging boulder problems. The additional screw hole offers a wide variety of setting positions and ensures a more secure attachment to the wall in your climbing gym.
