Camelbak

Did a 90 mile ride on a hot humid day and these bottles kept my electrolyte and carb drink cold long after my insulated podium bottles would have. Also, appreciate that I'm not worrying about the plastic leaching into my drinks on hot summer days. Couple caveats that made me lower to 4 stars. I needed new water bottle cages because one of the bottles popped out of the carbon cages over rough roads which are plentiful in New Jersey. Fortunatly the cheaper recycled cages worked well and I'm not worried about them popping out anymore. One of the stone colored bottles, which looked great when I got them, was scratched up pretty good when it came out on a ride and both are getting a little scratched up in the cages. Still look decent, but you're probably better getting the stainless steal. Overall, the fact that my drinks stay cold made them worth the buy.

These water bottles are clearly on the expensive side, but well worth the investment! I ride in the Phoenix AZ heat and it has always been a challenge to stay hydrated without drinking hot water or energy drink for the second half of the ride. These bottles keep the beverages cold! I have ridden for 4 hours in the heat and still have ice in my bottle at the end of the ride. I highly recommend this water bottle. If your water bottle cage is on the loose side they can rattle around and be pretty noisy, but on 2 of the three bikes I ride regularly they didn't make any noise at all. After I changed cages on the third bike to composite, tight cages the rattle stopped completely on my third bike. Now I don't hear any difference when I use these bottles.

I've bought various water bottles--plain and tepidly insulated--the latter lasting about twice as long as the plain one. Where I live we have microclimates, when I leave the house it can be 63' and eight miles inland 85'. This mean my ice filled insulated bottle water starting is fully melted at the 1/2 way point and will become rather yucky on the way back (and I still have another 500 feet of elevation to climb coming back. The Camelbak Podium is an excellent way to quench ones thirst on a hot day on my return leg, as it maintains the ice cold temps for two hours easily when kept full and makes the return so much more pleasant. It's a little heavier and rattles in my plastic water bottle cage, but a thin strip of Velcro dampens out the sound.

Expensive. It keeps my electrolyte liquid cold for over 4 hours while riding in 85+ degree (F) weather. Works 2 hours longer if you put about a 3/8" water on the bottom and freeze it overnight before use. The bottle is noisy if you put ice cubes in it, if your water bottle cage is a little loose, or on very bumpy roads. The bottle keeps cold at least twice as long as a Camelbak's plastic thermal bottle with about 25% frozen liquid in the bottom.
