This airbag backpack uses the new Alpride E2 electric system which is lighter, smaller and easy to recharge without gas cartridges but with micro USB or batteries. In addition, this bag is made of 200 deniers Dyneema®, a light fibre which is among the world’s most durable. You’ll have easy access to the content of this mountaineering backpack thanks to its access zip on the front allowing full opening, or the roll top closure on the front. Offering enough volume for excursions of one or two days with a night at the hut, this ski backpack is geared to carry skis, ice axes, a probe and a shovel (in its own compartment), and much more.
