Arcteryx Voltair 30 Avalanche BackpackGear
In the case that you are caught in an avalanche, this product will save your life. This backpack uses an electric centrifugal blower. It is powered by a rechargeable LiPo Battery. That helps it achieve identical pressure and fill speeds as traditional systems, but with additional benefits. One of the key benefits include pulsing of additional air once full, so it keeps the 150 litre balloon inflated even in the event of hit/punctures from rocks. And no worries, it checks out fine with TSA, since it’s not gas compressed.
