Using the Kinto tumbler technology, the Factor Travel Tumbler keeps drinks hot and cold for 6 hours. Vacuum insulated, the Travel Tumbler makes transporting your hot coffee, tea, or mineral water safe and easy. It ensures that the liquid will maintain the optimum temperature for the longest possible time. The flavor will also be protected thanks to the naturally BPA-free stainless steel interior. Even on the hottest days, your water or energy drink will remain as cool and tasty as if straight from the refrigerator. Please note that the Factor Travel Tumbler is easy to clean using soap, water, and a soft cloth. No abrasive sponges should be used, and it is not dishwasher safe. It also should not be placed in the microwave. It should not be used to hold carbonated beverages since the carbonation could cause damage once the top has been closed tightly enough not to leak. The silicon rings that come with the Tumbler should be correctly attached to ensure a tight seal for the cap. Whether you need a way to transport your favorite morning beverage to the office, or like to have a drink stay cool on longer bike rides, the Factor Travel Tumbler from Kinto will quickly become your favorite hydration aid.
