Mammut Assist Belay Resister

The Mammut Assist Belay Resistor is a clever training tool designed to improve belaying confidence, control and safety when using assisted-braking belay devices. Developed to reduce the impact force transmitted to the belayer during a fall, it helps create a smoother catching experience while encouraging better rope management and dynamic belaying techniques. Ideal for climbers with a significant weight difference between partners, beginners learning to lead belay, or instructors working with new climbers, the Assist Belay Resistor provides additional control without compromising the natural feel of the catch. Compact, lightweight and easy to integrate into your existing climbing setup, it offers an extra layer of confidence whether you're projecting routes at the crag or logging sessions at the climbing wall. A valuable addition to any climber's safety system, helping both belayer and climber focus on performance rather than weight disparities.
