After contacting the vendor, I now love my Coldest bottle. I didn’t fill the bottle full of ice the first time. So after filling it full to the brim then filling it with water I am happy to say that I can have ice cold water all day. I have hot flashes so I am always in need of ice cold water. I’m hoping this will last in hot sun while on vacation. I’ll have to wait and see. This bottle really does keep the water cold just remember to fill it up with ice first.
