Bigger than I expected so will fit lots of gear. The top zipper is funky because the cardboard, or whatever is used on the top piece keeps sticking out and I have to push it back to get the zipper to work. Then, when I get the zipper closed, the cardboard folds up. It is like it is a bit too big for the size of the opening. I have been away for seven weeks so I have only transferred my gear from my old bag and haven’t used it. I hope it will loosen up cuz right now it is a pain. If it does, I will revise my review.
