The raddest kit in rescue situations.
Petzl's RAD System has the rappel cord, locking carabiners, sling, and ascenders that backcountry skiers and mountaineers need for crevasse rescues, rappels, and glacier rope-ups. Its 30m Rad Line hyperstatic cord has a superlight, super-skinny 6mm diameter designed specifically for ski mountaineering. The Attache carabiner has a compact design, and Petzl includes three of these screw lockers for secure safety.
There are two ascenders, one chrome-plated Tibloc ascender for use as a progress capture, and Petzl's versatile Micro Traxion. The ultralight Micro Traxion is a capture pulley with sealed ball bearings and locks that double as a standard pulley for big wall climbing and solo top roping. Petzl also included its lightest sling called the Fin'Anneau, and a storage bag with webbing loops for harness attachment and holders for ice screws.
It's surprisingly convenient that all this gear stores compactly in the bag, and that the bag can compactly fit at the bottom of any ski backpack. This system should be a requirement for any mountaineer on mountains like Rainier, Hood, or Denali, but any backcountry skier can find convenience with Petzl's RAD System, especially if your partner gets stuck under a tree.

- Q & A
Sweet rope and compact system
- Familiarity: I've put it through the wringer
The RAD system is a super nice addition to my ski mountaineering gear. All the equipment fits into its storage bag and can be clipped to a harness.
The rope is super impressive on its own and it didn't ice up at all. Obviously being a thinner diameter, prusiks require 4 wraps rather than the standard 3 wraps. My only wish is that the rope was 40 m instead of 30 m. But Petzl has some great tutorials on its website and shows you how you might combine two of these ropes and other fun tricks.
The RAD system will definitely be coming with me on my next ski mountaineering trip and I will recommend it to others.

Cheaper than buying everything separately and comes in a convenient little bag. The rope is the most amazing part. Combine with a skinny 30m half rope and you have a pretty versatile alpine system and if you are just anticipating rappels or crevasse travel just bring it by itself. Definitely going to be my go-to rope for ski mountaineering this season.
So, everything I've seen rates the micro traxion for a minimum of 8mm diameter rope. What makes it okay to use 6mm in this case? Can I use a 6mm tag line for hauling on a micro traxion?
