Andrew did a great job with that.
I like a pack you can wear a wide brimmed hat with (if you wanted)

.. guess that means 50L or less
Took a passing interest in a pack project on BPL mic,

I like the cord sleeve on the side pockets.
One interesting idea from the discussion was the use of an airbeam pad for the internal frame (apparently Granite Gear/Klymit make something along those lines (?))
The pad used is only a tiny thing, designed for the purpose but I was ruminating over the use of a neoair (on its side), making the main compartment designed to fit...
Anyhow, it's a good read, working through the guys previous packs to reach 'the worlds best'
pm if you want..
