Leki's Trigger 3D is a proprietary click-in system that connects your pole directly to a compatible glove or strap adapter. Unlike standard nylon straps, it features a release mechanism that detaches in multiple directions during a fall, helping prevent thumb and wrist injuries.
The big advantage over Leki's older Trigger S system is multi-directional release—it lets go from more angles, giving you better injury protection while still feeling totally secure during normal skiing. That's why it's popular with aggressive skiers and racers who push hard and fall harder.
Two things to keep in mind: you'll need compatible Leki gloves or strap adapters, which add to the overall cost, and the system comes at a premium price. If you've ever jammed a thumb or tweaked a wrist in a pole strap fall, or you ski aggressively enough that crashes happen, the Trigger 3D is a smart investment in safety and convenience.
