Great pack for everything
This pack rocks. At 28 liters it is small enough for school or commuting to work, but big enough for a day hike. I use it for commuting, here's why: I can carry just my laptop (in the provided sleeve non the less) or I can stash my running shoes, shorts, shirt and water in there for a lunch time workout. The color is awesome (Lemon Lime) and is still dudely enough for a dude.
Ah, buy it!
