Product Details


210D Cordura Polyamide RipstopA synthetic fabric with 3 times the abrasion resistance of other typical polyamide fabrics. While durable and incredibly robust, it remains relatively thin and lightweight.


REACTOR SystemWith a total airbag capacity of 150 L (2 x 75 L each), combined with a dual inflation system, the REACTOR insists on security and reliability. The airbag's shape and positioning have been designed to maximize upward mobility in an avalanche. The inflation system is more efficient, compact, and lighter, while at the same time addressing the demands of real case situations. You also have the possibility to take the REACTOR system out of your backpack and transfer it into another compatible REACTOR backpack.
