Special for free touring skiing, this new 40L backpack integrates the latest ALPRIDE 2.0® avalanche safety airbag system, even lighter and more compact. Ideal for multi-day ski tours, this large volume bag holds shovel, probe, crampons, rope and bivouac equipment while offering several carrying options for greater versatility in practice. On the slope, its contact back ARIAPRENE™ offers breathability and comfort, meeting the resistance standards required by the CE standard. Reliable and easy to use, just pull the chest handle to activate the compressed air cartridge which then inflates the 150L balloon in only 3 seconds. This provides greater lift, which minimizes the risk of burial.
