    Does what you want it to do.

    Light-weight, drinking spout works well. Feels pleasant to use. What's not too like!

    Great Bottles

    Compact bottles with flex. Completely leak-proof and easy to clean. The fact that they only take up the capacity of the water they contain is bonus for lightweight travel where bulk also counts.

    Perfect design

    These are absolutely excellent. Lightweight, they don't leak at all, the water flows really easily when drinking. There's nothing not to like!
