💦🌞❄️ Performance Fabric
Made for days that start hot, get stormy, and end cold. Breathes well, wicks fast, and won’t stay wet. Light enough as a top, warm enough as a layer.
Great Sand Dunes is a landscape shaped by wind and imagination. You can hike a ridge thinking you’re close to the top, only to find another crest waiting. This tee traces the dunes, Medano Creek’s wide path, and the mountain backdrop that keeps the whole scene anchored. Anyone who’s run down a slope laughing, watched lightning dance over the range, or come early for sunrise will recognize the map’s familiar sweep.
Breathable, quick-dry fabric makes this shirt practical on warm sand or breezy afternoons, and the UPF50+ protection is welcome when you’re far from shade. It’s a simple, durable layer for people who know the dunes aren’t just a novelty—they’re a place where families, hikers, and stargazers all find something unexpected.

This is a lightweight, comfortable tee built for long days outside. It’s soft, breathable, and quick-drying, with a bit of stretch that makes it easy to move in. The fit runs a little generous, so the size guide will help you find what feels best.
The fabric is steady and durable, holds its color, and won’t shrink in the wash. It’s the kind of shirt you can wear on the trail, on the road, or anywhere you spend time outdoors.
Made from 95% polyester and 5% spandex, the material meets the highest ultraviolet protection rating under the AATCC TM 183 test. We can share the documentation if you ever want to take a look.
