As a longtime user of insulated, double walled water bottles, I can wholeheartedly recommend “The Coldest Water” bottle. Here are some of my reasons:
THE CAP. The cap is fantastic. Hydro Flask makes some bottles with the same sized mouth opening, yet their screw caps are only as large as they need to be. I really like the enlarged cap on this. It allows you to grip it easier and get it on and off faster, with less effort. The carabiner loop at the top is also nice and wide, which makes it easier to slip your fingers in and carry it by the top of the cap. It is also nice to know that the hydro flask cap (they call it the hydro flask standard mouth loop cap) fits, just in case you happen to need a new cap and aren’t able to get one from The Coldest Water for some reason.
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!
One of the only negatives I can come up with for this bottle is that the gasket seal in the cap is pretty deep in the grooves and could be tricky to get out and clean properly. I will be using this bottle for water, primarily, so I don’t expect that I will need to worry about this too much.
