Query: Small mouth is the way to go

For a long time I had a large mouth Nalgene bottle that I loved. The ONLY thing I didn't like was the huge mouth that caused me to spill water all over myself if I wasn't really careful. This new small-mouthed size bottle is PERFECT! It is still a tough lexan bottle with an attached top, and classic colors, but now it is more practical to actually drink from. Hopefully I won't lose this one too!
