Jason G.wrote a review of Arc'teryx Mantis 26 Daypack - 1587cu in on May 26, 2012
This pack has turned into my go to day pack. I've had it for about a year and use it for everything from a day hiking pack to carryon luggage (where it probably gets more abuse). No issues, zippers still work well and a small , no fabric tears and the sleeve is sufficient to fit a 13 inch laptop with no problems. The upper zippered pouch is a great place to store keys, camera, and anything else you would grab frequently. Just hiked in CO this weekend, and other than wishing the waist strap had some padding, the pack performed much better than a "commuter" pack should. Plenty of room to stuff a rain shell, spare socks, soft shell and a 1.5 L bladder.
