Designed for involved missions in avalanche terrain the ABS A. Light E Set 18L provides everything we need to stay prepared while remaining compact. This DWR coated polyester bag keeps our gear dry when faced with snowfall boasts multiple carry options allow us to boot pack with our skis or board and provides an avalanche tool pocket so that we can get to our gear quickly in the event of an emergency. Speaking of emergencies the high-speed fan deployable airbag allows us to traverse slopes with a little more peace of mind--after checking the reports and digging a pit of course.
