As noted, the pack shown was used only for the prototype and we are developing our own special purpose pack. The pack shown happens to be a Mountainsmith Challenger Day Pack. The pack we are developing will be custom produced to our specifications and is still under design as we consider various options. Volume will be 1900-2000 cu. in. and it will generally look like a day pack. Our aim is a pack that will stand up to considerable abuse, protect the components of the kit, be carriable by a handle and optionally as a pack with shoulder straps if it is necessary or desirable to move from a crash location (which we generally do not recommend except in extraordinary circumstances) and is lightweight. It will likely be red on top and black on the bottom. That is really all I can offer at this time.
