The Gossamer Gear Air Beam Pack Frame, a joint venture between Gossamer Gear and Klymit, is an inflatable pad sized specifically for use with Gossamer Gear packs. After some measuring, I purchased the size “Medium” for use with my Murmur Hyperlight pack. The sizes for the Air Frame correspond to the GG pack sizes, but since the Murmur is one size only, I had to guess which one was best.
The medium frame weighs in at 3.5oz on my scale (including the pump). This is almost double the weight of the SitLight pad that was included with the pack, but I think the Air Frame is much more functional. The SitLight works just fine, but isn’t very rigid. Sometimes it gets scrunched up if the pack isn’t completely full. The Air Frame can be inflated with a fair amount of pressure and helps hold the shape of the pack much better.
Just like the SitLight pad, the Air Frame can double as a sit pad, and I’m fairly sure that this could also be rigged into a pillow . So, despite the weight penalty I think you can make up for it by leaving a pillow at home. You could also use this for additional hip or lumbar padding when you sleep.
The shell material seems sturdy, so I’m not terribly worried about punctures. This also seems like it will hold a fair amount of pressure without a blowout. The bulb-style pump works well enough, but it does require nearly 100 squeezes to fill the Air Frame to maximum pressure.
At first glance, there is only one thing that could use improvement. There is no way to seal the pad and remove the pump. I’m sure something could be rigged up with a little ingenuity, so that you can leave the pump at home without the pad going flat.
I will report back once I’ve carried my Murmur with the Air Frame for a few miles.
