Very lightly used Skywalk Flex. Original plan was to use it with a dedicated hike-and-fly setup, but I never followed through with that and only used it for kiting days (because it’s so light) and a couple flights up in Monterey.
Airbag portion is detachable, so it can be a minimalist hike and fly kit or a still very light setup with protection. 4.4 lbs with the airbag attached. The reserve is a chest mount setup (no reserve included).
