Features vacuum insulated body and foam insulated lid to keep beer cold for hours. Made of 18/8 stainless steel and BPA free. The heavy duty handle makes it easy to carry and allows you to pour smoothly with one handle. Steel inner lid means no plastic is in contact with your beer. Dishwasher safe. I have this growler and it’s awesome. See: Hands On: Stanley Classic Vacuum Insulated Growler! – includes temperature trials.
