Great Bottle!

I was skeptical of this bottle being that it's Mainstays Brand, however, I was surprised by the quality of the bottle as well as the performance. It keeps my drink cold for hours, and if I use ice, the ice doesn't melt right away even when it's hot outside. The other thing that I do like is that it doesn't sweat at all!! Great buy in my opinion!

I like it.

I like it.It is slimmer than some bottles 32 oz and hold alot of water.I like to have a skinny bottle because fat ones is harder to hold on to.
