Camelbak

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.

It's pricey but I live in the southeast and the summers are hot. On one hot summer day I left this bottle along with the gf's Yeti Rambler water bottle in the truck in direct sunlight. When I came back to the truck, this Camelbak bottle was colder. Both had a small amount of ice in each when I left but only this one had any left when I returned. Even road rides, this bottle has maintained cold, icy water for hours in 100'+ weather. It's a bit different to not be able to squeeze it but nothing you won't get used to in a couple rides.
