No matter whether you need your drinks to stay chilled or toasty warm, this mug has a vacuum insulated body that will do the job, keeping the contents hot or cold for 3 hours and iced for 20 hours. Crafted from 18/8 stainless steel, it will never rust and is leak proof and car cup compatible. The integrated D-ring lets you clip to packs for total convenience. This mug is also dishwasher safe, for hygienic deep cleaning. In 1913, William Stanley invented the all-steel vacuum bottle. Since then, the Stanley vacuum flask hasn't missed a day of work, a football game, or a trip to the great outdoors. The durable double-wall stainless steel insulation of the distinctive Stanley vacuum flask is iconically American and still works as hard today as it did nearly 100 years ago.
