If you're into personalizing - or if you're the sort who loses pieces of things - you can buy replacement lanyards and caps in different colors.
To drink from the bottle, you turn the cap so the water droplet marks are aligned - it's a sipping cup rather than a straw bottle.
But wait! There's more!
Well, maybe not more about this particular bottle, but Polar Bottle has a bunch of other styles of bottles, including custom designs, if that's what you're looking for.
Who's it for: Thirsty people.
Pros: Pretty colors. Unbreakable. Insulated. Affordable. Lightweight.
Cons: The website doesn't mention if it's dishwasher safe, so I'll assume it's not.
Wishes: I wasn't super-crazy about the lanyard, but it's removeable. Some folks might want one, though. So there ya go.
