Good idea, leaky valves |

I received 2 of these bottles with my Speedgoat bum bag. The bottles do a good job of being pliable enough to be easy to use, but stiff enough to hold shape and make pushing back into the bag pouches easy, plus standing upright by themselves.
The bottle valves are disappointing though. Whether through design or control of tolerances, mine leak: with a full bottle held in the orientation of the Speedgoat pouches and without pressure on the bottles, I get a wet back until I've drunk sufficient to lower the fill level.
If the valves were better, these would be ideal bottles. Bite valves made to a specification which prevents leakage are available fro mother manufacturers, and it's a shame the Ultraspire ones haven't equalled them.
