Mainstays 40 oz Stainless Steel Tumbler with Straw and Handle, Double Wall Insulated, White

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.

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!
