My 32oz and 64oz Nalgenes are a decade-old and I routinely freeze water in them -- filling the water to about an inch. No problems.

I left a bunch of bottled waters in the car all last winter. Stored them in a soft-sided cooler in case they did leak. Temps down to the teens.

No problems. No leaks.
