Key Features

• 18/8 Stainless Steel: Rugged, rust- and puncture-resistant, this kitchen-grade steel is built to withstand the bumps and drops of the road.

• Double-Wall Vacuum Insulation: Keeps your drink cold, no matter how hot the day gets. Whether you’re on the move or enjoying a slow morning, your refreshment stays just right.

• Dishwasher Safe: Hydration is hard work enough—this mug is ready for easy cleanup, so you can focus on your next adventure.

• Reusable Straw + Lid: No more single-use straws. This BPA-free, shatter-resistant straw is ready for repeated use, and the molded stopper keeps it securely in place.

• Elongated Handle: Big enough to handle large sips, yet perfectly comfortable to hold — even when you’re juggling keys and camp chairs.
