Our lightest, thinnest, dual-certified half and twin rope, the 7.8 mm Photon gives new meaning to the saying, less is more.

Pair the Photon with any of our certified single ropes, on routes with long rappels for an extra layer of insurance. Now available with new DryXP treatment, UIAA-Certified Water Repellent.
