Put your bladder to the test and announce to the world that you have a serious caffeine addiction and/or that you will need to stop to use the bathroom every 15 minutes. Like our other RTIC products it is vacuum insulated, double walled stainless steel and comes with our awesome logo laser engraved upon it. It should keep you hydrated for your 12 hour shift, and will keep ice for much longer. It has two sized openings for filling or drinking and a convenient carrying handle. We're not saying you should, but a growler, by coincidence, is 64oz.
