Mammut Smart 2.0 Belay Device – Dark Ultramarine

Trusted belay performance with minimal setup

Since the Smart belay devices first entered the market in 2009, Mammut has built on real-world use to refine braking, geometry, and handling. The Mammut Smart 2.0 belay device leverages that experience to deliver improved braking effectiveness, optimized geometry, and intuitive operation. The brake system is designed to engage when needed, while the belaying action remains aligned with a climber’s reflex movements.

Core advantages at a glance

• Extremely lightweight at 80 grams, making it easy to manage on belays, especially during long sessions.
• No moving parts or levers, contributing to a clean, reliable operation you can trust.
• Tube principle supports both lead climbing and top rope setups with consistent control, even in dynamic moves.
• In a fall, the brake insert locks the rope and works with the belay carabiner for solid support and enhanced safety.
• Recommends pairing with the Smart HMS; compatible with rope diameters from 8.7 to 10.5 mm, covering common sport and trad ranges.

Beyond the specs, the Smart 2.0 is designed for real-world handling. Its compact form stays close to the device, reducing snag risk and keeping your belay line clean. Belayers can focus on timing, communication, and pace rather than fiddling with the mechanism.
