Nice and compact but limited space
The reason I bought this airbag pack is because of the shape of the airbag. Basically it is like a giant life jacket that wraps from each side of your chest all around the back of your head. Definitely the best design as far as trauma protection. It is a small pack that can fit minimal gear so best used for sidecountry, heli, or short day tours. Because some of the airbag is stored in the straps it takes a little while for the straps to break in but overall it is quite comfortable.
