The Smart 2.0 is a purpose-built belay device that blends lightweight handling with reliable rope control. Weighing in at just 80 grams, it delivers a crisp belay feel without any moving parts or levers to fidget with. Built on Mammut’s hands-on experience since the original Smart model debuted in 2009, the 2.0 variant adds improved braking effectiveness and refined geometry for intuitive handling when you need it most.

Real-life use scenarios

At a crag with mixed routes, the Smart 2.0 stays securely in hand as you feed rope smoothly and lock off confidently after a catch. In a gym setting, its light weight and predictable action help you keep focus on your climber’s progress rather than fiddling with hardware.
