I found the nemo gogo replacement air bladders at
for 11 bucks a piece and in stock, so.......
I decided to go with this to start out,
hopefully they will be the right size,
or I'll just have to make them fit!
this should get me farther into the prototype/design phase
and let me know for sure that this idea will work.
it works on the gogo and morpho tents ......
next I'll sew in something to hold the "airbeams" in place (once I have them)
cool, a freestanding blackbird bivy ...... perfect !
