Because the Tim Teufel stickers on your Jansport are starting to peel off anyway, snag one of these just-released back satchels from Topo Designs, a CO-based outfit that throws together a "Western/mountain aesthetic" with "high-end fashion", though they could just be being literal, as those things are actually made, like, 3000ft up. Steal Phil Plantier's debit card and buy yourself:
The Mountain Bag: This pretty mama is perfect for weekend travel or as a "take-to-work bag", and features laptop padding, a waterproof lining, and lower cinch straps "for securing extra gear", unless that ish is Metal, and solidly snakes around your... whatever, either way, great game.
Daypack: Perfect for both "work/travel" and "camping/hiking", this sack is 12"x16"x6" and comes in colors including black, khaki, olive, silver, and duck camo, although if that's what you have to do, it kind of defeats the original purpose, right?
Klettersack: In case you want to look at people with the Daypack and demeaningly exclaim, "my bag is taller and has considerably more volume", snag this hiking-focused cinch-top number, which frankly beats the hell out of the 20 that Teufel wore.
