💦🌞❄️ 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.
Mount Rainier dominates the skyline, but the park’s spirit shows up in the details—wildflower meadows at Paradise, deep forest trails, and the sound of meltwater rushing down rocky creeks. This tee maps the mountain’s major approaches and the familiar roads and trails that circle its lower slopes. Anyone who’s stood at Sunrise on a clear morning or wandered the shaded paths near Longmire will immediately recognize the landmarks.
The lightweight performance fabric works through changing temperatures and shifting mountain weather. UPF50+ protection helps on high-elevation trails where the sun can be stronger than expected. It’s a comfortable, reliable layer for people who know Rainier is more than a mountain—it’s a presence, visible from miles away and unforgettable up close.

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.
