Frequently Asked Questions

How do I clean and maintain my SMMT tumbler?

We recommend cleaning any of our Sèrpa Tumblers with warm, soapy water immediately after use. Gaskets can be removed carefully for more thorough cleaning.

All Sèrpa Tumblers are dishwasher safe

Are SMMT tumblers dishwasher safe?

Absolutely! Our Serpa Tumblers are built tough with 18/8 stainless steel, making them dishwasher-friendly for easy cleaning after a long day of adventures. For those who prefer a gentler method, hand washing with warm, soapy water works beautifully too. Whichever way you choose, your tumbler is crafted to endure and maintain its peak performance.

Are SMMT tumblers made for warm or cold beverages?

Yes. All SMMT Tumblers are designed for insulating both warm and cold beverages.

What is the warranty on SMMT tumblers?

At SMMT, we craft products with the utmost attention to quality and durability, built to withstand the rugged mountain environment. 

To ensure your gear is up for the challenge, we offer a Limited Lifetime Warranty covering manufacturing defects and material failure for the expected lifespan of the product.

Please note that the warranty does not cover wear and tear, washing/heat damage, or damages caused by alterations or third-party services (e.g., airlines). If you have a warranty claim or need more information, you can start the process here.

What makes the Serpa Tumbler better?

The Sèrpa Tumbler is the result of an obsession to make the absolute best insulated drinkware on the planet. The innovative design of our Sip & Stow lid system and 3-Way Insulation was driven by the need to go farther for longer. A design profile inspired by Park City’s ranch & mining heritage and a commitment to premium and sustainable materials make the Sèrpa collection standout from the crowd.

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

Is this tumbler really healthier?

We think so.

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

Is the Serpa Tumbler 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.
