This Boulder Travel Mug is ready for filling with 64 ounces of ice cold craft beer at the brewery or fresh hot coffee from home or your local coffee house. Featuring our TriMax® triple insulation technology, this bottle is vacuum insulated and tested to keep iced liquids cold for up to 36 hours and hot for up to 8 hours. We've included a removable stainless steel infuser, so you have the option of adding the flavour of fresh fruit to your drinks. If you’re a tea enthusiast, fill the infuser with leaves, and the Boulder Travel Mug will be your favourite tea maker. On a summer day or warm evening, pour some wine in the growler, add slices of oranges, limes, pineapple and enjoy refreshingly chilled sangria that will stay cold all day - perfect for taking on a picnic or day at the beach!
