If you want to climb with someone lighter or heavier than you, this assisted belay resistor is the answer. The lightweight device attaches to the first quickdraw and increases rope friction, allowing a lighter belayer to catch and hold a heavier lead climber's weight. Thanks to the patented cam construction, only a fall or lowering motion activates the resistance, and the rope is never blocked completely. Instead, the device facilitates smooth handling and soft catches, allowing it to be used effectively for dynamic belaying. Take on new routes with confidence with the Mammut Assist Belay Resistor.

Increase rope friction with Mammut Assist.

Mammut Assist is rated for mismatches of up to <77 lbs when clipped to a quickdraw, or <99 lbs in Boost mode with a locking carabiner. During a fall or while lowering, its cam mechanism activates, increasing rope friction.

The redesigned best-selling Ophir harness collection, our light yet tough helmet range, and our 9.8 Crag Recycled Classic Rope are built to perform when it counts. People might question your life choices – but you know you can trust our climbing equipment.
