I found this pretty one at Walmart , but the reviews say the water doesn't come out very well.
This one is at Target, but the review says the thread on the cap don't fit the metal mouth of the bottle well. Too bad because it's a good price and I like it.
The water bottles at Simple Luxuries comes with a loop cap and a sports cap.
Amazon.com has many of the above and others like these.
Okay, after I got the kids involved in the search, we found way too many to put in one post. This should have been titled "More Water Bottles Than You Ever Wanted to See".
