Why the Serpa Tumbler

The Serpa Tumbler is our take on the modern insulated cup – crafted for mountain days and the moments earned after. Inspired by Park City’s mining heritage and shaped by timeless design, it blends 18/8 kitchen-grade stainless steel, vacuum insulation, and a patent-pending steel lid system into one refined, functional vessel.

Why It’s Different

  • Patent-pending double-lid system with magnetic nesting steel lid
  • 18/8 kitchen-grade stainless steel with no interior coatings
  • Small-batch production for elevated quality control
  • Designed for both outdoor adventure and après gatherings

Why It’s Healthier

  • BPA-free components
  • Non-reactive stainless steel interior
  • Dishwasher safe for proper sanitation
  • Built to replace disposable cups

Why It’s Worth It

The Serpa isn’t mass-produced trend drinkware. It’s a considered piece of mountain utility—crafted to last, designed to elevate daily rituals, and made in small runs to protect quality and intention.

Care Information

Do not microwave. Fire or injury may occur.

Leakproof Seal:
Do not use with Dry Ice.
Do not use with Carbonated Beverages
Do not use for storage of perishable food.
These uses can cause pressure to build inside the vessel. If pressure builds up, the cap can be difficult to remove or forcefully eject and cause harm.

"Best tumblr I have, out of many!

I love that the lid actually seals properly, I don't have any worry about leaks and the lid fits snuggly on the bottom when I don't need it. Also is great at keeping my drinks the proper temp for a long while."

– Justin

EL3VATE™ Thermal Protection

This is more than vacuum-sealed insulation. SMMT Serpa Tumblers provided 3-way insulation to keep your drink at the perfect temp.

01 Lateral double-wall insulation uses 2-layers of vacuum-sealed kitchen-grade stainless steel to block temp escape.

02 Our patent-pending double lid system prevents temp loss from the top.

03 Base-up surface separation: the nesting-cavity in the tumbler’s base provides a conduction barrier from resting surfaces where significant energy exchange occurs.

SIP+STOW™ Double Lid System

Our patent-pending, 100% leak proof lid system is made from two engineered parts: a stainless steel upper lid which magnetically stows in the base, sealed away from dirt and debris, and an inner-lid ergonomically designed for pleasant sipping, made from high-end, BPA-free Tritan polymer.

Connecting The Action To The Pause

Our mountain-environment shaped a simple obsession: a better insulated tumbler to enhance the moment of pause. Designed to get you through your active days and elevate the moments when you slow down.

Reviews

Good tumbler, needs stronger magnet

"I like the tumbler. It keeps the drinks cold and holds ice for a long time. Its also a good size for cup holders in the car or otherwise. I loved the idea of the lid magnetizing to the bottom but the magnet isn't very strong. Even a little agitation and the lid falls off of the bottom."

Matthew S. (4/5)

Heavyweight

"The tumbler was a staggering disappointment, utterly unlike anything I expected. It is shockingly heavy—so burdensome that carrying it feels like hauling a weight, and using it becomes an awkward ordeal. While it may serve some people well, its astonishing heft completely overshadowed everything else and left me profoundly frustrated."

Scott K. (3/5)

"Love it. I use it every day. Great to fill with water and a little ice and throw in my backpack. Ice stays in for hours. Would love to see a 20oz version for my coffee in the mornings. Same diameter but just a little taller. Also works great at storing my little debbies out of sight from my kids. Star crunches and fudge rounds fit great."

jesse (4/5)

"Awesome designed cup. Easy drining and with the locking lid you can shake up the contents. Oh did I mention the coffee or ice drinks really stay hot or cold by the time you drink it all. The only think I wished they made it in a 24oz."

Richard (5/5)

Giving it a shot

"So far it’s alright. Not necessarily impressed with having to twist the cap to be able to drink thus far, guess just very used to the Yeti’s. Haven’t dropped it yet or tried hot liquid in it either, the cold tea has stayed cold this afternoon."

Grant F. (5/5)

It’s fine

"It’s a good cup for coffee, I would not spend $60 for it tbh. It’s nothing insane it’s just a more expensive tumbler. The build quality seems fine but most brands offer the same build quality. Idk there was a lot of hype around that and it’s just normal honestly"

Jason W. (2/5)

"I love this cup, instantly became my daily driver coffee cup. There are a few small tweeks that I think could be made to make is perfect but I love it none the less!! Will more than likely buy more"

Benjamin (4/5)

"I love the sturdy feel of it. I carried it in my work bag. It did great! It didn't leak. I'm pleased with my purchase and will probably order another one for my spouse."

Vicky (4/5)

Great Travel Cup

"The design is highly refined, and the lid system stands out as the most impressive feature of this cup. From the top cap to the magnetic base for storing it, the concept is carefully considered. It is certainly leakproof and will maintain ice cubes and liquid at a cold temperature for most of the day. ."

Jason B. (5/5)

Product never arrived

"Shipper confusion Customer derive were quick to respond then stopped being quick. Told me if their investigation didn’t produce any results they would ship replacements, that deadline came and went and never heard back. Using DHL and USPS as last mile is not good : this order have conflicting tracking info and I had to go to post office to inquire. Overall inconvenient Not a good first impression and I still don’t have a refund or replacements. . . waiting patiently. At this rate I want a refund"
