The wide rope-bearing surface, clipability, deep basket, and auto-locking gate of the Superfly Evo Auto make these carabiners a must-have for the weight and performance conscious. They are large enough for gloved use and feature great action, all in a weight that can shave significant weight off your rack. Updated with a snag-free keylock nose and auto-locking gate, making for an even easier to use lightweight locker.
