I stopped using the Camelbak bottles a few years ago. There was always trouble cleaning the mold from the valves. Camelbak has supposedly solved this problem with the new easier to remove jet valve. The smaller size (by 1 oz) is a little easier to handle than the previous model. I filled up one bottle with ice, topped it off with water, and my water was cool up to 2 hours in mid 90 degree temps. I filled up the second bottle with water and put it the freezer overnight. Topped it off with water before my ride and the water was ice cold when I reached for it after my first bottle was empty. The water tastes good also, not a plastic after taste like some bottles. For info-the Elite Custom Race cages are a perfect fit for these bottles. Nice snug fit, you won't lose a bottle, and no more rattles.
I ditched my old Camelbak Podium Big Chill bottles after dealing with mold in the valve several times. The new Podium Chill bottle has a new valve that is easy to clean. It's shape is easy to grab out of your bottle cage. I ride in 90o temps during the summer and it keeps my water nice and cold. I full them up with ice first and then full with water. When I grab for the second bottle, usually around the two hour mark, it's nice and cold. The only complaint I have is you have to squeeze hard to get water to come out, and it's near impossibe to get the last 2 or 3 oz of water out without taking off the cap and drinking it like its a water glass. The taller shape made me lower the bottle cage on my seat tube as low as it would go, otherwise it would hit the top tube when I withdrew it ( I have a compact frame). I have yet to find a perfect insulated water bottle, but this is close to it, even with the couple of complaints. These work very well with the Elite Custom cages.
The shape is nice and it is easy to get in and out of the cage. Not too tall to cause any problems in my 54cm frame. BUT if this is insulated, then I am Chris Froome! Ha! Water gets warm just as fast as an uninsulated bottle. I leave before sunrise to start rides and the water is always warm within 30 minutes or less.
Works as well as the older model podium chill, but is taller. I like the drinking nozzle better - easier to drink from and to clean. However, it is taller, so harder to fit in some of my bike bottle holders, and doesn't seem quite as tight.
Best bottle I've used. Replacing the 2 I've used for almost 2 years. Never had any cleaning issues.
This bottle is 1000 times better than any free bottle and more than likely made with much better plastic.
If you have limited space, go with the 21oz model.
I purchased this for the higher volume since I sweat a lot. I also appreciate it being easier to reach and remove since it is taller. Fitting with the frame was not an issue on my gravel bike because the bottle mounts are lower to allow a top tube bike packing bag.
Been using podium bottles for years. The design has actually improved over time. Great bottle. The only problem is that by ordering this here, you will receive a random color, and living in a sunny area, black (the color I received) is the only color I did not want to receive.
I have owned several Camelback water bottles and they have worked well ( Not Leaking ). The last 2 bottles I have purchased have leaked at the lids. I would have returned them but the return shipping costs would have been more than the price of the bottles.
