Lowe Alpine Quark 40

This is a very light pack and has the most minimal framesheet, but excells with a heavy load. I've put 5 textbooks, water, and other junk in there and still been comfortable. Because it's not a huge pack, on longer trips I took advantage of the daisies and the other straps and loops and i've attached just about everything imaginable in every possible configuration from large boxes to bike helmets to climbing rope.

The roll-top design took a little while to get used to, but I've really come to appreciate it. It really keeps junk from falling in and allows for extension in a way other pack designs do not. I strongly reccomend this pack for light weekend trips, or as a day pack. I've used it for everything from a light hydration pack on a run, to a full winter backpacking trip on which iI packed it way past capacity and was still amazed at the level of comfort.
