I had a 48 oz Nalgene Cantene that I brought on a week long backpacking trip into the Sierra's last summer and a buddy noticed there was some water leaking onto my pack. I had the Cantene in an outer pocket and discovered it had a small leak near the top of the bottle- if the bottle got squeezed it would leak some water. I kept using it and if I filled 3/4 of the way and was careful not squeeze it, it did OK.
When I got home, I rechecked the leak and decided to just toss it.
A couple of weeks ago I had another Cantene on a 5 day trip in Arizona, again a buddy noticed leaking on my pack- the culprit- a 32 oz cantene, again in a side pocket. Leaking at exactly the same spot and again, just a minor leak.
Anyways, I've just gone ahead and will now use regular Nalgenes. The weight savings over the Lightweight Nalgenes isn't a lot and I've never had one leak (including dozens of heated ones in my sleeping bag on extra cold nights).
Here is where they both leaked (could be the other side, just drew one arrow)
