First impression
We already had the opportunity to briefly test the LiTRIC system over a year ago, and were of course all the more pleased that the backpacks with this pioneering system is now available in a wide range of versions. The base unit is very light and compact for an airbag system and is easily stowed in the upper part of the rucksack. The rucksack can therefore be filled easily, regardless of the zip-on, and does not have to be packed around the airbag system like a tetris, as it is sometimes the case with competitor products. Of course, the option of recharging the system at home has major advantages. Additionally, there are no costs or effort involved in procuring cartridges and the system can also be easily transported on an aeroplane. Furthermore, test deployments, of course, are much more frequent if you only have to pack up the airbag again afterwards. What's more, the airbag system is produced entirely in Germany, which is always nice to know.
I had two Zip-Ons available for the test, the rather compact Freerider 18 and the rather large Tour 40. The former is actually very compact and can therefore only be used for ski tours with really very small equipment, but of course its area of use is also freeriding in the ski resort. The Tour 40, on the other hand, can really hold a lot of equipment and is therefore also suitable for demanding tours and multi-day tours (at least if you are based in huts). Both attachments have an outer compartment for valuables or small items, the Tour 40 also has its own compartment for avalanche equipment, while the Freerider 18 has an inner compartment for this. Of course, skis can also be attached to the outside, diagonally in the case of the Freerider 18 with stowable straps, while they can also be attached to the side in the case of the Tour 40. Both zip-ons have a stowable helmet holder.
