Nice Water bottle

I left my other water bottle at work and needed another. This bottle keeps the water cold even the next day. I put ice water in about 12:40 in the afternoon on Sat. On Sunday at 8:20 in the morning it's still cold even though I still had a little water left over from the day before. That means a lot to me. It tells me it works!! It's also tall.

Great cup for water drinkers

If water is your drink of choice, this LARGE 40 oz cup is what you need to own. It has a stainless steel inside and a plastic outside. The lid screws on and the only way to drink out of it is the tough plastic straw. If you don't want to drink out of the straw, you can unscrew the lid and drink out of the cup. Be aware that if you spill it, EVER YTHING will get wet!

GRAB THIS - Wonderful!

40 Ounces. Insulated, and kept my drink nice and cold for 5 plus hours outside - even though the temps went to the mid 80s', and the cup is BLACK... I was a bit surprised my drink was still cold under the blaring sun on a cloudless day! Fits into a regular vehicle cup holder - built in or add on, long so if you have a deep built-in cup or add on holder in vehicle, this will fit perfectly! The lid is a twist to shut, but I never had the need to shut it, comes with a nice thick reusable straw... I did place the cup in the freezer for a quick chill - held up fine, whatever water or tea I didn't finish, would be refrigerated, and surprisingly, still fresh!
