If you're looking for a pack that can handle rugged day hikes then turn around to join you on your daily commute, look no further than the Patagonia Black Hole 25L Backpack. It's made with Patagonia's tried and true Black Hole fabric, which delivers bombproof durability and highly water-resistant protection to keep your gear protected from any and all challenges of the mountain or the town. From overgrown trails to overcrowded subway cars, this burly ripstop fabric won't quit, while smart storage features keep your extra layers, gear, and everyday items organized and secure. There's a padded 15-inch laptop sleeve to hold your computer or tablet in place during bumpy bus rides, and a set of stretch mesh pockets on either side so you can bring your water bottle and coffee thermos along for the ride. A special port at the top back panel accommodates hydration bladders for scorcher days on your favorite trails, and daisy chain loops on the front provide convenient lashing points for extra gear.
