Nice bottle, but has it flaws
I bought this bottle primarily because it's insulated (without the size of a giant, round insulated bottle), and because the holder was less cumbersome than most of the new Nathan bottles. The only two drawbacks are that 1) this is NOT an 18oz bottle as advertised (it holds no more than 16oz, filled as high as it will go), and 2) the lid can be difficult when removing, and easy to cross-thread when closing. Otherwise it's a very nice ergonomic bottle that will keep your drink cold (I live in FL). If you need more than 16oz though, this is not the bottle for you.
