The  Camp Photon Express KS is purpose-built for onsight climbing where every gram and every second counts. The lightweight Photon carabiners are optimized for fast action and smooth clipping. The proprietary SphereLock closure is an upgrade to the traditional keylock system with an even cleaner nose profile. The Photon Express KS also uses our most sophisticated dogbone with variable width webbing that makes them easy to grab while projecting sport routes and the proprietary Karstop Evo carabiner retainer on the rope end. Available in 11 and 18 cm lengths.
