Was thinking it would be nice if the top pocket was removable, maybe on adjustable straps, like you mentioned, where it attaches or something , then have attachements on the frame so you could just use the frame and pocket if you wanted for some reason. Just a thought, may have been mentioned before.
Asked above about barreling. Zero barreling with this s pack and frame. On of the main factor's of my purchase. Also something he above mentioned the top lid fully covering when the snow collar is completely extended. This is the ONLY ISSUE I have found. My feeling is they need to make the lid on straps so it can be extended to cover a huge load. Not a deal killer for me at all as I absolutely love the pack. Just something that should be addressed on a further run.
