Yes. Follow three tips to keep it from splitting:

1. Fill it only ¾ full. Water expands as it freezes, and a full reservoir can split.
2. Don't drop it while frozen. Cold makes the material less flexible, so an impact can crack it.
3. Add a little cold water after freezing. It loosens sharp ice shards that could puncture the film.

Then enjoy ice-cold water on your next adventure.
