2025 Limited Edition Winter White Release
Winter White Volume 2: Frost White is our 2025 limited edition release celebrating this winter season. The white purity of untouched winter snow and the frosty powder blue accent of ice blend the seasons' serenity with its chilly edge. Annually our most anticipated color for the most anticipated season. The Sèrpa tumbler is defined by our stainless steel, leak proof lid that magnetically nests underneath when sipping. The winter season is most magical with a warm beverage to start an active day and cool drink to finish it off. Only 980 made.
Features:
- Proprietary leakproof, stainless steel lid. Knurled edge finish.
- Designed for versatile, on-the-go winter enthusiasts and travel seekers
- Vacuum insulation keeps drinks hot or cold for hours

At SMMT Outdoor, we believe that great products are born from great stories. With the launch of our latest Winter White collection, we're not just unveiling a new color—we're sharing a journey of inspiration, craftsmanship, and a dedication to quality that meets the needs of those who live for adventure.

Leak-Proof, Steel Lid
Patent-pending, leak-proof steel lid with a knurled edge. This removable lid doubles as a coaster that magnetically nests underneath the tumbler.

Inspired Design
Our Winter White color was carefully designed to evoke the beauty of winter’s untouched landscapes. The brilliant white of fresh snow, gleaming under the morning sun, inspired the core of this new color.

Only 980 Available
Our 980 Limited Editions are only made in quantities of 980 (referencing the elevation of the mountains above our town). We release these to our community first, and when they sell out they are gone for good.
