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

Serpa tumblers can be cleaned with warm soapy water and are dishwasher safe.

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.

Do open periodically to relieve pressure.

"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

Sip & Stow™ Double Lid System

100% leak-proof patent-pending upper steel lid magnetically stows underneath the cup while you sip. The inner lid made of premium Tritan polymer is designed for smooth flow and perfect sipping

3-Way Insulation™

This is more than vacuum-sealed insulation. SMMT Serpa Tumblers provided 3 distinct methods 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.

Elevate Your Chill

We craft refined outdoor drinkware for the moments between the action. The earned pause. The slow down. The golden hour. The afterglow. We design for connection, not simply hydration. Our tumblers perform at the highest level so you can relax at yours.

Exceeds expectations

"We love our Sherpa tumblers and have enough of them for everyone in the family. During long days backcountry skiing/climbing, our hot drinks stay hot and do not spill in the backpack. When we jump on bike to go to an evening concert or sunset ride, our cocktails stay nice and cold. It's a small feature but the top nests perfectly into the bottom and we've stopped the game of collecting orphan mugs/bottles that lost their tops. 10/10 recommend."

Best in Class Design & Great Gifts

"We love our Sherpa Tumblers and use them for morning coffee and happy hour cocktails. The design is refreshingly original and the no-spill lid has saved the day several times! A nice bonus is that these have become our go-to host & hostess gifts. Beats a candle every time!"

Chris H. (5/5)

"Really impressed with this tumbler. The build quality is nice and there was actually a lot of thought put into the design. The lid is amazing, no guessing when the liquid is going to enter your mouth. It's fast and predictable unlike some other brands where it's like turning on a hose in front of your face"

Travis D. (5/5)

My new favorite!

"I am super happy with this tumbler. I recently packed with hot coffee for a day out with kids, and did a great job. No leakage. Piping hot coffee hours later. Stylish design. I've had friends comment how much they like the design features and style, so I already ordered some to give as gifts next month. One caveat, you need a larger cupholder if you are going to use in a vehicle. My truck has larger cup holders, but my wife's SUV does not. Highly recommended!!"

Justin A. (5/5)

The new "Go To"

"The SMMT Sherpa 16oz Tumbler is my new "go-to" drinkware, such that I've picked up multiple colors over the past few months. I've been using the Dreamscape Blue as my daily driver for coffee (both hot and cold), High Meadow Sage as a camp traveler, and Triple Black for adult beverages. These work great in the car, around the campfire, and on the golf course. Love the mason jar design inspiration, the functionality of the leak proof lid, and the magnetic storage that doubles as a coaster. Well done, SMMT!"

Max M. (5/5)

Awesome gift

"Got as a gift, but it turned out to be the perfect mug that I didn't even know I wanted. It's summer and it's hot so I've primarily been using it to keep ice in a drink. With the lid off it does an amazing job of still keeping a beverage extremely cold, but with jut a tiny twist of the lid it will keep ice for me for hours. Love it. The magnetic lid storage is awesome and I haven't lost the lid yet because of it."

Drew (5/5)

Best in the market/exactly what I was looking for

"Over the years I’ve purchased countless tumblers & water bottles from all the top brands, and as soon as I got my SMMT tumbler I stopped using the rest. It is noticeable in how much colder it keeps drinks, for longer. And the topper & lid are such a unique, high quality design - it brings luxury and functionality to an area that’s been a miss with so many other products on the market. The overall design stands out too (yes I get compliments and questions when I bring it to the pool). SMMT is such a visible step above the other brands, I haven’t shopped any of the others since I discovered it. Thank you team SMMT!"

P. A. (5/5)

Great colors and quality

"Love this product, such a unique and beautiful design. Definitely turns heads. Keep up the good work."

Chris (5/5)

Incredibly high quality

"Everyone that touches this comments on how high quality it feels -- it's definitely a cut above a typical tumbler! The fit and finish as well as a few of the features (like the built in coaster) make it special."

Sunil N. (5/5)

"Cup will not sit flat in my car cup holder (its too fat). The lid is hard to take on/off. And drinking through the plastic part? Ick. I wish the lid worked without the plastic sippy piece. Not for everyday use, for me. 2 stars for cool design."
