Klean Kanteen’s insulated tumblers have quickly become one of our favorites around the Tailwind office – because who doesn’t like to pound some coffee or tea after a morning run, ride, or whatever you choose to do? These insulated tumblers are the best coffee mugs in the morning, keeping drinks hot up to 6 hours. And, for an afternoon workout or when the work is done, it’s time for a cold beer and these insulated tumblers will keep drinks cold up to 24 hours! Heck, if you are traveling you can also throw in a Tailwind stick pack with some water to make sure your electrolytes are in check. The best part? It comes with the Tailwind logo!
