Winter Session makes these two-tone canvas backpacks. I like the fact that the bottom panel is a waxed canvas. I have accidentally put many a backpack in some crazy gross shit. That's on my unobservant ass. But I've also been in situations where some asshole around me just spills their whole everything all over the place and stained a really nice tote bag that I got for free. Just remember, you can't get too aggro when someone kicks over a drink or spills stuff. Why? Because, inevitably, you will be the guy that spills his whole everything ruining someone else's gratis tote bag. Instead of being judgmental, be prepared. And keep your belongings aka laptop aka actual personality in some waxed canvas.
