The Edelweiss Oxygen II 8.2mm sits in the number one spot for a half rope with its very low impact force and weight. For being a soft catching and light rope, the Oxygen II puts up a giant fight against the rock and water, thanks to its HC Cover and Supereverdry treatment. The HD Cover greatly reduces abrasion and snags while allowing the rope to run fluidly through protection and across the rocks. The Oxygen II comes standard with the Supereverdry treatment that is polymerized onto the sheath and core fibers, making it highly water and abrasion resistant. Weight: 43 gm Impact force: 5.5kN UIAA falls: 8 SE Supereverdry Unicore Process CE and UIAA Certified Half Rope Note that this item of climbing safety equipment is non returnable.
