The Gossamer Gear Air Beam Pack Frame is a removable, adjustable, inflatable pack frame that will fit in any Gossamer Gear pack.
Add the Air Beam to your Mariposa, Gorilla, Kumo or G4 pack and get a light weight frame that can also be used as a sit pad (on appropriate ground) or rolled up and partially deflated to make a pillow.
With the Mariposa and Gorilla you may want to remove the metal stay first for weight and comfort to suit. However with all the packs this does give you the opportunity to stuff the pack and the Air Frame into your flight bag so that on arrival overseas you can build your pack ready for the hike. (Very useful)
The firmness of the pad is adjusted using the attached inflator bulb and can be done on the fly. The Air Beam Pad comes in three sizes S-M-L. The pad size corresponds with the size of your pack. Each pad comes with a repair kit and the attached but removable inflator bulb and connecting tube.
