I got this pack in the blue with green lettering. I fell in love with the colors and, knowing that I love my other compressor pack, was sure it would be great. Wrong. The straps just didn't sit well on my shoulders. I am female, 5'2" and semi petite... definitely made for broader shoulders. I couldn't see myself using this as a daypack and being comfortable. Also, the mesh pockets on the side seem totally useful but the elastic isn't as tight as, say, Ospreys side pockets, so things are bound to fall out if the pack isn't upright. I filled it and threw it around a bit before I decided to return it. The front mesh pocket is also a great idea, theoretically, but same issue. Stuff fell out, i.e. nutrition bars, pack of gum, headlamp, etc... Unless you fill it to the max, the only support is in the back (which is super stiff - didn't like that either). I wanted lightweight day pack with compression ability but I think I'll stick with my current compressor, as it's not as long and big on me.
The last thing I didn't like was the stiffness of the straps. I was hoping for more of a mesh, less padded strap for light weight, easy throw on, carrying. If you like the padding, it's awesome!
If you're a guy with shoulders, and probably not going to toss the bag on the ground multiple times, I'm sure you'll be fine. I prefer zippers or tight elastic pockets so I don't lose things.
