The Pro R.A.S. ready is described by Mammut itself as a professional backpack. R.A.S. stands for Removable Airbag System. This means that the airbag can be installed and removed very quickly. This means that the backpack can also be used very well without an airbag, or the airbag can be built into a smaller backpack! It is described as a professional model, as it was specially developed for mountain guides. In other words, there are many attachment options and with its 45 liters it offers plenty of space for various equipment.
Overview
Very robust and well thought-out backpack with a few fine extras! A 6 mm aluminum U-frame holds the backpack in place and prevents it from collapsing. Tidiness is half the battle and there are plenty of storage options to make life on the mountain more pleasant. However, I would particularly like to highlight the rear access to the main compartment.
The layout
A front pocket for avalanche safety equipment with an extra large flap on the zipper so that it can be opened quickly with gloves in an emergency. Inside there is also an SOS label with emergency instructions.
The large main compartment can be opened completely from the back and from the top. There is also a compartment for the hydration bladder on the side of the main compartment, although this is very small and I never used it.
A top pocket, which is very spacious and allows quick access to goggles etc.
Additional side pockets on the right and left; practical for crampons, skins or a water bottle.
A hip belt pocket for a small camera, energy bar or knife.
The fastenings
Ski holder diagonal: the size can be adjusted on the lower flap. Works quickly and easily. When it is not needed, the lower strap can be stored in the backpack.
Board or snowshoes are strapped on vertically using the snowboard holder. The holder must be attached separately, but makes a solid impression.
Two ice tools can be attached and the two lower straps of the holders can be stored when not in use. The holder can also be used for trekking poles.
The helmet holder has a snow guard and can be completely removed when not in use.
