The mountains obey their own rules. Security cannot be bought, and the best life insurance is the careful choice of the safest lines, up or down. However, despite having the best preparation the risk still remains and accidents still do happen. This is where the ABS airbag system comes into play.
Take a box of cereal and give it a shake. You will notice that the smaller pieces of cereal will move to the bottom of the pack and the larger pieces of cereal will remain towards the top. This principle is called inverse segregation and means that in the case of an avalanche the larger particles remain at the top of the flow. A kilo of snow has more volume than its equivalent in human body mass. The Twin airbags of ABS give you the added volume which you need to stay atop the avalanche debris, or at least, be buried less deep. The Twin Bags of ABS have an added volume of 170L which will make you so to speak one of the larger particles in the avalanche.
An ABS airbag avalanche backpack cannot replace mountain safety courses, a buddy system or an avalanche transceiver. However it can and does influence the body when caught in an avalanche, and thus is a valuable addition to any touring or freeride equipment.
The Swiss Institute for Snow and Avalanche Research SLF has proven that avalanche airbags considerably reduce mortality rates in avalanches. An inflated airbag system means that the chance you will be killed in an avalanche by half. The Company ABS are the originators of the Avalanche Backpack and with 30 years of experience by far the longest experience in the field. In just under 300 registered cases with the ABS Twinbag system, there has been no serious injury to the head, neck or back. The ABS twin airbag backpack offers superior protection in case of an avalanche, when used in combination with a transceiver, shovel, probe, helmet and back protector. Speaking of which, you can integrate a back protector into the ABS pack, killing two birds with one stone. Really good, right?
