THE BEST TUMBLER: The insulated Hydro Flask 40 oz Travel Tumbler is here to hydrate more and refill less. The insulation keeps drinks cold and the durable handle takes it to the next level. The perfect size stainless steel tumbler bottle can go anywhere, even fitting most cupholders. Cold stays cold, and the flexible straw is easy to sip any which way.
COLD STAYS COLD: Thanks to the double-wall vacuum insulation, drinks stay cold for hours. The Temp Shield insulation delivers cold hydration anytime so your morning fill is the perfect temp.
LEAK-RESISTANT: The leak-resistant press-in lid with straw on the insulated Travel Tumbler keeps drinks ready to sip. The Flexible Straw lid is soft on teeth and easy to flex so you can sip any which way.
FITS CUPHOLDERS: The cupholder-friendly design means your water tumbler fits seamlessly in most cupholders. Designed for seamless cupholder cohabitation, it's right at home on the open road, on the sidelines, in a pack or wherever you need to set your sips.
PURE TASTE: Durable pro-grade stainless steel ensures pure taste and no leftover flavor transfer. So, today's water won't have any taste of yesterday's iced tea.
DISHWASHER SAFE: Easy to use and easy to clean, just disassemble the straw lid from the cup and toss it all into the dishwasher. Designed to keep bright color, being dishwasher safe means your favorite Hydro Flask is always at-the-ready.
