If Apple made a tumbler, this would be it. We test out a lot of cups and tumblers here at Engearment, but the MiiR Tumbler is just simple and sexy. Made of 18/8 medical grade stainless steel (like most vacuum insulated tumblers we test) and featuring their proprietary Thermo 3D Double Wall Vacuum Insulation Technology. This tumbler keeps liquid cold (or hot, if that’s your thing) as many other insulated cups do, but it dishwasher safe. That is a pretty big deal. Lots of people are too lazy to hand wash dishes, and if you are one of them, then this is your vacuum tumbler. No judgment from us if you don’t like washing dishes!

MiiR is a stand up company and they donate 5% of revenue (that’s a big deal) to clean water projects, bikes and education across the globe (55+ trackable giving projects!) So you can really feel good about supporting a company like MiiR. You can track your impact too. On the bottom of each cup is a tracking number that you register on their website. Very cool system. We hope that many other companies follow in this manner.
