Mammut Smart 2.0

Dark Ultramarine

The Mammut Smart 2.0 is a cleverly designed, lightweight and easy to use assisted braking belay device ideal for sport and wall climbing. 

Deservedly popular and extremely compact and lightweight, the Mammut Smart 2.0 features no moving parts or levers and sits perfectly in the hand. Working like a normal tubular belay device, the well designed brake inserts interact with the belay carabiner making it easier to lock the rope in the event of a fall. This maximises safety for single rope lead climbing and top-roping through improved braking effectiveness. It is also easier to pay out rope faster to the lead climber due to the compact geometry.

Ideal for indoor climbing and sports climbing the Mammut Smart 2.0 provides increased safety and handling on rope diameters from 8.7 to 10.5 mm.

Smart 2

Lighter in weight cf the Smart 1, a great device to give additional security when belaying a heavier leader. Instinctive to use after a traditional belay device. Can be used with a good range of rope diameters. The shorter leaver initially feels less sensitive whilst lowering.

Excellent Product

Having managed with a standard belay device for the best part of 30 years and avoided 'Gris Gris' type devices. I am totally pleased with Mammut Smart 2. Have used it to arrest falls, top roping and leader belay. No problems at all. It is very safe with minimal slippage and is safe in the hands of a learner. The default is to attest the rope which it does very well. I'm not sure how it would manage descending, I will probably stick to my belay plate or figure of 8. Highly recommended.


added confidence and easier on the hands

I bought this after my climbing partner took quite a big fall. I didn't drop him or anything but it was just one of those things. I thought I'd give a new device a go instead of my ATC and thought I'd try this out of the assisted braking ATC style devices. A Gri Gri or other similar devices just seemed like a bulky faff. I really like it. I find paying out to be super easy and lowering too. It is definitely less tiring than holding someone whose hanging on to a draw whilst resting with an ATC which is nice too. The catch from a fall is pretty sudden on the 9.8mm rope I'm using at the moment so I am trying to improve my dynamic belaying too which is fun. Overall, feels like a decent bit of kit.
