I have been piecing together this design for a few months now, primarily in the form of a cycling pack for commuting. I thought I would like a day/summit/ultralight bag that payed homage to the 1990s as well as Japanese backpack design (which I am really hot on right now).
This bag is spectra/cordura, which is above all else a high quality weave and nice, thick PU coating on the back.
%100 Coats thread, 1" web throughout and heat sealable packcloth I picked up from Seattle Fabrics to make the dry bag.
No powder skirt on this one, but have been considering it for the future, or possibly an integrated roll top/dry bag unit.
Thanks for looking!
