Popping up to New York for a bit next week and thought I'd make a real simple carry-on bag. It's based around Delta's max bag dimensions: 22x14x9". 1000d Cordura nylon. Unlined.
Should've made the handles a bit longer.
One compression strap.
This is my first zippered backpack. Usually I'm not a big fan of this design because zippers are pretty fragile, but since the zipper doesn't go all the way around this bag it can totally fail and the bag will still function. And, as you can see, it opens plenty wide.
