Does The Job

  • Familiarity: I've used it several times

I got two of these to stuff in the pockets of the Mountain Hardwear Fluid race vest and they fit well in the front pockets. I wanted a light-weight collapsible bottle and these are just that. The bite valve does't leak but they do have a slight funky plastic taste, although that is not a deal breaker for me.

Odd bottle, but I'll take it

    This is an odd little bottle. I bought it so I could put it in my pocket while skiing. It doesn't hold much water, but keeps me hydrated while skiing for a couple of hours. I didn't get the plastic taste like the other person commented. I'd say if you're looking for a solution to light hydration needs that are super compact it isn't a bad bottle.

    Tastes like plastic

    • Familiarity: I've used it several times

    Too small (feels like a few sips and water is gone), mouthpiece can slip off causing water to spill all over, water has tasted like plastic since I got it. Will be returning.

    Could be improved with a wider diameter or more oval shape to allow for larger vol of water and change the mouthpiece/top of bottle to make the top slimmer and mouthpiece better stabilized.
