Bontrager's Messenger Eco Bag makes hauling your gear easy. Made from recycled bike tubes and old banners, it's waterproof and super tough. An internal sleeve holds a 15-inch laptop and an external zipped pocket keeps essentials close by. The shoulder strap is adjustable, of course, and you've got anti-sway straps to keep it in place as you head up Broadway. It even has reflective accents for visibility.
