Pack an extra water bottle with all your work gear inside the Patagonia Women's Chacabuco Backpack when you have a hope of sneaking a hike in at lunch. The pack's water-resistant fabric protects your laptop, tablet, and other electronics when you forget to tighten the water bottle all the way down. Bungees make this backpack highly versatile, with the ability to store bicycle helmets as well as yoga mats and more—whatever you have to look forward to that day.
