Here's what other sites are saying:
For leashless mixed or competition climbing, attach the Cassin X-Dry Grip to your Cassin X-Tool. The two ledges allow stacking and swapping hands during your calculated moves on vertical or overhanging ice and rock. Cassin designed the X-Dry's tough, dual-density polycarbonate grip without a spike for speed climbing and comp applications.
An interchangeable hand grip for your CAMP X tool, the X-Dry Grip has two ledges and a minimal spoke with teeth for leash-less climbing and dry tooling.
