A Sustainable Insulated Tumbler Unlike Any Other

When it comes to insulated tumblers, we’re well aware that you have a ton of options out there. But how do you choose the best insulated tumbler? Pirani Life makes the best insulated tumblers on the market, not just because of our superior vacuum insulated technology, but also because of our commitment to a more environmentally-friendly lifestyle.

When you choose a Pirani Life vacuum insulated tumbler, your drinks always stay cold (or hot!) and the party spirit stays alive. Plus, you can feel good knowing that by using your favorite reusable party cup over and over, you’re helping prevent the unnecessary spread of harmful plastic pollution across our planet, especially in our oceans. Let’s find out more about just how Pirani Life is the best insulated tumbler you can buy!

Easily Stackable

One of the most annoying things about other insulated tumblers is storing them. You know what we’re talking about. You stick them in your cabinets, but they’re bulky and one can hardly fit inside the other, so they become too tall to fit in the cabinet. Or what about taking them with you to work or to a friend’s holiday party?

With the Pirani Life reusable party cup, those concerns are a thing of the past! All of our insulated tumblers are easily stackable — just like your favorite red party cups of old. Conveniently store all of your reusable party cups in the cabinet or even stack them up and bring them to a party, camping and anywhere else you choose!

Triple Insulation For A Cold Drink and Dry Hands

At the end of the day, the most important thing you’re looking for from your insulated tumbler is to keep your favorite beverage cold or that morning cup of coffee hot. Pirani Life has you covered! Our reusable party cups use exceptional vacuum insulation technology, using skinny walled triple insulation with a special copper coating to eliminate your cup from “sweating”. This allows your drinks to remain at the perfect temperature, without the sweaty mess!

Maintains Temperature

Thanks to a cutting-edge vacuum insulation technology, Pirani Life stainless steel insulated tumblers are guaranteed to keep your drinks hot or cold, your hands dry and the party spirit alive. Our reusable party cups maintain temperatures to keep your drink cold for 12+ hours, hot up to 6 hours and do not sweat.

Vacuum Insulated

Vacuum insulation works by not allowing heat transfer by any of the three ways it travels — radiation, convection or conduction. This is accomplished by double walls that create a vacuum, which heat cannot travel through. We also added an internal copper coating to increase insulation by 10-15%.

18/8 Stainless Steel

Pirani reusable tumblers use ultra-high-strength 18/8 stainless steel, which along with providing supreme durability does not transfer flavor to the beverage the cup holds.

BPA Free

Our vacuum insulated tumblers are completely BPA- and phthalate-free, making them safe to use and non-toxic. This is also true of the lid, made from Tritan — an indestructible plastic.

Rolled Lip

Nobody enjoys looking like they have a hole in their lip. We’ve made drinking from our reusable party cups a breeze thanks to a rolled lip, which delivers the smoothest drinking experience.

Made With Premium Quality For Long-Lasting Durability

The whole point of buying a reusable party cup is so you can use it forever without the need for single-use plastics. That’s why we built our insulated tumblers with premium quality from start to finish. This guarantees that no matter how often you use your reusable party cup — and we expect that’ll be a lot — it holds up to your standard of performance. The cup itself is sturdy with a powder coat finish and so is the lid, which is completely indestructible!


When buying a stainless steel insulated tumbler, you want one that stands the test of time. Our insulated tumblers were built to last a lifetime, backed by a lifetime warranty. We also use a powder coat finish for easy grip and maximum durability. They’re even dishwasher safe!


Pirani Life reusable tumblers were designed to go wherever you go, making them the ultimate portable companion. Our reusable party cups hold 16 ounces (473mL) with a 3.75-inch diameter (9.5 cm) and fit all standard cup holders.

Conversation Starter

Thanks to the look of your favorite red party cup and a variety of colors and personalization options, you’ll find that your Pirani insulated tumbler is quite the conversation starter. People can’t help but ask about your reusable party cup at social gatherings. Not only is it effective, portable, durable and eco-friendly, but it might also help you make a new friend or two!
