Add the significant safety advantage of an airbag to your sidecountry/cat skiing/heli skiing setup with the Ortovox Free Rider 20L S Avabag Kit Airbag. Perfectly sized for days when you only need the basics, and including the new Ortovox Avabag system (cartridge is necessary and sold separately), the Freerider 20 S has a super clean and close profile so you can rip those big lines with a fresh feeling of confidence. (The "S" denotes a short back length, suitable for riders of smaller stature).
