As a longtime user of insulated, double walled water bottles, I can wholeheartedly recommend “The Coldest Water” bottle. Here are some of my reasons:
Another plus for this bottle, in my opinion, is that they’ve set themselves apart from the competition by being a little more unique. They’ve added a grippy silicone band at the bottom of the bottle. This is an added little bonus, because it is removable and looks great with or without it.
The opening is large enough for standard sized ice cubes, yet this bottle will even keep tap water cold for hours. I like this bottle because the 21 ounce size is great to keep at my desk. I fill it up several times a day from a water fountain or water cooler and the water will stay nice and cold for the morning or afternoon.
I see no reason to suspect this bottle is inferior to the other top brands in any way. In fact, I actually prefer this one!
Note: I received this product at a discount in exchange for my honest review. I have not been compensated by the company in any way and these are my unbiased opinions.
