Less complicated a bag's design - Mystery Ranch Kletterwerks Market Backpack

I have owned many backpacks over the years, and I've decided that the less complicated a bag's design, the more versatile it becomes.
This bag proves the rule.

The addition of compression straps prevents the usual "sag" that happens with top-loading bags, where the contents of a partially-loaded bag settles into a lump at the bottom of the pack.
