"Lightweight locking carabiners are hard to come by—especially full-size. The Photon Screw Gate accomplishes both brilliantly. The full-size design is easy to use even while wearing gloves making it a great choice for lightweight mountaineering and alpinism. The sharp nose profile easily slips into and out of webbing and old pins making it ideal for setting up snag-free anchors.
