Mammut Smart 2.0 Review

Passive assisted braking devices have elicited a lot of "whys?" from people when they spotted us testing them out at the crag. Think of them as a cross between a GriGri and an ATC. If you're partial to tube-style devices but want some extra holding power and security, then the Smart 2.0 is a great choice. If you've always used a GriGri but are open to trying something lighter and less expensive, the Smart also fills that bill.
