I have 4 of the 96oz Nalgene Canteens and in one year of reasonable (but not heavy) use I have had 2 failures — both of the same variety.
The failure point is where the flexible plastic joins the solid block at the mouth. Just pinholes and seems to be a fatigue failure from folding them up in my pack.
I loved them — they were light and *seemed* more durable than some of the alternatives, but unless I can figure out how to stow them in a better manner and make them last as such I'm going to have to give up on them.
Bummed.
