Just because your day will be spent wandering city streets instead of the usual backwoods trails, doesn't mean your daypack won't require a durable construction. The Mystery Ranch Prizefighter 21L Backpack has the toughness, comfort, and organization you need for both daily adventures and far-flung travels, with a size that's ideal for day-long excursions. The rugged Cordura fabric more than withstands the bumps and bruises of city life, and also resists snags and scrapes when you finally get to escape to the mountains for a long day hike. A full-length plastic frame sheet and comfortable harness help you support heavy loads, and a padded 15-inch laptop sleeve ensures that your computer or tablet will stay in place on winding bike commutes. Other storage features include an internal document and tablet sleeve, as well as two zippered pockets on the front to stash maps and smaller pieces of gear.
