There are so many brands out there now, especially after everyone realized the toxicity of BPA, but the Thermos hydration bottle is the best of the bunch. If you put ice into this in the morning it is very likely to be there the following morning! The rubber-like base gives it stability in addtion to protection from dings. The mouth is wide enough to hold all but large ice cubes, so there is no need for special "ice tube" trays. It looks rugged, and it is, but the most superior quality this product demonstates is the ability to keep your cold drink cold for a very long time. It fits my car's cup holder, but it might not fit all. That hardly matters because the easy opening click button means you can quickly sip and close, reassured that this never, ever leaks! The bottle is pure stainless steel, inside and out, so no worries about anything leeching into your drink.
