Bergans Y MOUNTAINLINE 40 Daypack S/M – Your reliable companion for alpine adventures with integrated Safeback SBX avalanche equipment. This high-performance backpack combines functionality with life-saving technology: The patented Safeback SBX technology continuously pumps fresh air into the snow cover and directs it straight to your breathing zone – a crucial advantage, as suffocation is the main cause of death in avalanche accidents. With 6 lithium AA batteries, you get 90 minutes of runtime, even in extreme temperatures down to -30 °C. The optimized air pump provides you with enough oxygen to maximize your chances of survival in the critical first 15 minutes after being buried. Thoughtfully designed for mountaineers and freeriders who take safety seriously and want to rely on their equipment.
