Now then, next review should be of the Camelback Podium . The best bottle I've ever had in 30yrs!
1) The jet valve is so easy to use. My other bottles had a valve I have to pull up to open, which is quite distracting. Afterwards I had to push it down again or it would leak. Not so with this Camelbak. It has a leak-proof lockout position, but even with it open it wouldn't leak, even with the bottle lying near horizontal on my top tube bottle holder (Bike Friday). So basically, no locking/unlocking needed at all for me at all while on the bike!
2) It slides out and back into my bottle holder much more easily than either bottle I had, even the one that came with the bike (Bike Fridays come with a bottle).
I may end up getting another one of these to replace my other bottle that is still working but is smaller and less convenient than the Camelback Podium.
