ROCKY MOUNTAIN TUMBLER™ keeps beverages ice-cold up to 24 hours and
piping hot up to 12 hours! Double-wall, vacuum insulated design holds a
whopping 30 oz. and is made of heavy-duty, 18/8 stainless steel that is
virtually indestructible. Easy-view lid has a sliding spill guard. Fits
standard cup holders. BPA-free.
This is great, it will keep ice cold for hours as well with hot drinks. I love this.
