It appears to be a nice functional design but mine leaked in my pack. I discovered the O-gasket seal in the cap moves out of position when tightened. I thought it was an isolated case but when the second flask did the same thing, I replaced it with a 16oz Nalgene HDPE narrow mouth screw top bottle & the problem went away.
