Sport Water Bottle,Unibott(TM) Tritan Water Bottles BPA Free Lead Proof for Outdoors Cycling Camping School Kids-Wide Mouth

Not entirely happy. I didn't know you have to total ly unscrew the top each time you need to get a drink, such a hassle. Couldn't return since its pointless to get charge to ship it back almost more than what I paid for.

Nice product. It seems to work very well.
