Huge, space for all of my stuff and some of my girlfriends.
Secure... well designed frame and strap system.
Comes with rain cover which is a must have.
Needs more pockets, forces you to combine items in to 1 main pockets, 1 bottom sleeping bag pocket, 1 large brain, and 2 side pockets. I would love a pocket or two on the hip belt or at least one more smaller to keep your little stuff easily accesible and not hidden underneath your large items.
Non detatchable brain: my girlfriend has a very similar pack and hers has a detachable brain for a day pack which is an awesome option and saves her from having to turn a dry sac into a day pack which is what I do.
Straps: Personally I'm not a huge fan of the material that the straps are made out of, they are slightly abrasive and could be improved.
Overall, I am happy with the product I got, especially for the price I paid.
