The Tour 30L Removable Airbag 3. 0 adds safety, not weight, to our kit. The enhanced harness system and stabilizing U-frame give us a comfortable, distraction-free carry on the climb, while the thermoformed back panel sheds spray on the descent. Built with the pursuit of pow in mind, this pack comes equipped with Mammut's compact, ultralight Airbag System 3. 0 which features a height-adjustable handle that, when pulled, deploys the bag to full in just 3 seconds.
