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!

I wear a CPAP mask at night and like to have cold water to drink without taking off the mask. This bottle keeps water cold for a long time, and the straw can slip under the mask edge so I can sip some without taking off the mask. It will leak if rather full and ripped over while the straw is in. And the lid is a little fussy to get started right. If the kid isnt on perfectly even, it will leak if tipped.
