I have a Gonex zippered bag that I suspect is from the same exact manufacturer.

I cut some stuff off and its about 8 oz. Its a pretty good day pack or beach pack, and you can easily fit an overnight load in it if you so pleased. Side pockets arent durable but the holes in mine so far havent affected performance.

Its not as good as a Flash 22, but its also a third the cost. I got mine as a gift in one of the UL secret santa gift exchanges, but its a lot of backpack for the price.
