Sea of Dreams Under the Rainbow Magic Mug

Celebrate Sea of Dreams, a technically challenging climbing route on Yosemite’s El Capitan, with a design that reveals itself as your drink heats the mug. At room temperature, the glossy black exterior keeps the artwork hidden. Add hot coffee, tea, or cocoa and the colorful Under the Rainbow design emerges.

Original art design by Jeanine Moorman.

This 11 oz color-changing magic mug brings the drama of El Capitan to an everyday ritual. It’s a distinctive gift for climbers, Yosemite fans, coffee lovers, and anyone inspired by bold routes and big-wall adventure.
