Lighter and more compact than the previous version, the Mammut Removable Airbag System (RAS) 3. 0 increases efficiency on demanding uphill tours, and inflates in a mere three seconds when deployed in the event of an avalanche. Its height-adjustable, T-shaped deployment handle provides a more ergonomic release trigger for easier use. The brightly colored airbag provides great visibility in avalanche rescue scenarios where large debris fields are present. For maximum convenience, the RAS 3. 0 quickly and easily swaps between different Mammut packs. Plus, there's a safety leg loop that keeps the pack firmly attached in the event of a traumatic slide.
