Rocky Mountain Tumbler: The tumbler that keeps your drinks colder, or hotter, for longer

The tumbler that keeps your drinks colder, or hotter, for longer

Rocky Mountain Tumbler is the best tumbler you'll ever own for keeping your drinks at the desired temperature for longer. The double-walled vacuum-insulated construction keeps ice-cold drinks fresh and cold for a WHOLE DAY, including overnight! Fill it with squash, smoothies, energy drinks or just water and you can head off on long journeys, on the hottest days, but still have an ice-cold drink as much as 24HRS later. Plus, thanks to the kitchen-grade steel, there's no metallic taste and it won't form condensation or 'sweat' on the outside like so many other steel tumblers.

When it comes to hot drinks Rocky Mountain Tumbler works brilliantly too with hot soups, coffee, tea, or any steaming hot beverage. Take it out in the cold weather and it'll still be piping hot up to 12hrs later. That's longer than most flasks!

With a spill-proof, self-sealing clear lid to see how much you have left and a clever tapered design so it holds up to 30oz but still fits into your car's cup holder, Rocky Mountain Tumbler is all the tumbler you and your family will ever need.

Double-walled vacuum-insulated construction

The technology that went into the design and construction of the Rocky Mountain Tumbler means you can even fill it with ice cubes and place it in boiling water, or even blast it with a blow-torch, and those cubes won't melt! The vacuum created between the inner and outer surfaces stops any transference of heat in either direction.

Premium 'kitchen-grade' stainless steel

There are different standards of steel and Rocky Mountain Tumbler is made from the very highest, kitchen-grade 18/8-gauge steel, used in industrial kitchen surfaces that need to be strong and hygienic. There's no metallic taste and it won't allow condensation or 'sweating' to form on the outside, soaking your hand, bag or clothes and losing precious heat.

Large, 30oz capacity but tapered to fit in your cup holder

Because Rocky Mountain Tumbler can keep drinks ice-cold for 24hrs, you can take enough with you to keep you refreshed all day. With a huge 30oz capacity you can enjoy as much as you like. Plus, the clever tapered design means that you can still fit it into your car's cup holder!
