Youll never want to drink water out of anything else, ever again. I mean, look at this guy. 22oz of Quadvac insulation, keeping your water or tasty cold beverage as cold as ice for up to 35 hours. Heavy duty doesnt even cut it either, as this 18/8 stainless steel killer is thicker than any other leading competitor bottle. Just pick it up - youll feel the difference. Not only that, this bottle is naturally BPA-free and dishwasher safe. You may clap now.
