The Acent 30L is an all new design for 2019/20 season. It's new lightweight design in ever sense gives you a feel of nothing on your back. It might be ultra light but it uses abrasion resistant materials so you';;never find your edges cut into it. There is also a built in spine protector that will give you protection if you are to have any falls on your climb or decent.
The Ava system is ORTOVOX's new lighter than ever before system, it inflates in no time after it is activated. It is a very clever design but is actually not a complicated one.
