Details

Designed in the Tetons. Built Through Adventure.

Most sun shirts start in a catalog.

Ours started on the river.

After months of development, multiple prototypes, and countless hours of field testing, the Heritage Sun Shirt was built to perform where it matters most. Every seam, every panel, and every feature was refined through real days spent fishing, rafting, hiking, and exploring.

Constructed from premium 150 GSM matte performance fabric, it delivers lightweight comfort without the glossy finish found on many performance shirts. An athletic tapered fit reduces excess fabric while maintaining unrestricted movement, and full flatlock seams provide long-lasting comfort and durability.

One feature we intentionally left unchanged is the double-layer hood. While the shirt dries quickly, the hood retains moisture a little longer, creating natural evaporative cooling on hot summer days—just wet it and keep moving.

This wasn't designed to follow trends.

It was built to solve problems.

Teton Series — Athletic Tapered Fit

Designed with a streamlined, athletic cut. If you have a larger frame or prefer a more relaxed fit, we recommend ordering one size up.

Looking for a roomier fit?
Our Outfitter Series is currently in development with a more relaxed cut designed for larger frames and broader builds. Field testing begins in early 2027, with release targeted for Summer 2027.
