Reduce Slim Cold1 Tumbler - Straw, Lid & Handle. Insulated Stainless Steel 40oz, Peachy Mint

Beautiful lilac color cup with easy open lid. Keeps my drinks icy cold all day long. When I wake up in the morning, there is still ice left in my cup. Lid parts easily come apart for cleaning. The cup only fits on the bottom rack of the dishwasher. I would highly recommend purchasing a straw cleaning brush..

This c up says stays cold for hours but I can say it stays full of unmelted ice overnight and drinks cold all day….I must say nothing lasts long enough in my cups to do the how many hours check! But at least 8 hrs is fair because by then already have done a full refill for the night. While I typically avoid anything but cups with screw on tops, this cup's top has stayed snugly in place without coming loose. I don't know how long that will last but at this point comfortable enough for me to keep next to bed or if fall asleep in bed. No middle night disaster or leak despite finding it on its side. I absolutely love this color. Exterior is pretty and comfortable to hold. There is no condensation on sides (and most importantly) no condensation on bottom of cup.
