Hi all, looking for some advice please.
My 750g Golite Jam pack is now nearing its end of life. I intend to MYOG its replacement - im keen on an external framed roll top- something like an zpacks arc haul with a sub 700g weight.
Most packs seem to be fabricated from multiple panels , even when the main body is fully rectangular.
I'm proposing to cut my whole bag from a single piece of fabric as per attached sketch. This would reduce seams , simplify the build and improve waterproofness.
Ive not seen this done before and it seems to be a good idea- especially as the throat and main body are the same fabric. Is there something I'm overlooking in attempting this simplistic type of construction?
Regards
Bill
