I got this bag as a gift, and Im very satisfied. Perfect bag for a light day hike. Its able to hang a light rain jacket off it, and enabled to utilize all the compartments within the bag.
The only downside to it is that it is tough to utilize all 3L of the hydration pack and somehow manage to zip it closed (never was able to fill it all up and was unable to zipper it completely w ease). If its filled a lot, its hard to use the big zipper pocket cause the hydration takes so much space bulging.
Yet, I don't fill it all the way (3/4 of the hydration at the most), and still am able to use most of the space. I just hang my shirts/jacket off the meshed sections, and stuff real little things in the zippered compartments.
Overall, Im pleased.
