“I used these shirts on a 3 week bike packing trip and they were great! They dried fast when I washed them and didn't smell at the end of the trip like my synthetic shirt.”

Born on the Front Range
Merino is known primarily as a cold-weather fabric, but it does both incredibly well. Our shirts are designed for everyday wear, even on the hottest summer days.
Wülf Wool makes one thing: a lightweight, 100% merino shirt. We’re locally owned, and every order ships from Fort Collins.
Yes. Merino breathes and moves moisture away from your skin, so it helps regulate your temperature as conditions change. At 140 GSM, ours is ultralight.
Will it smell after a few wears?
Merino naturally resists odor, so you can wear the same shirt more than once between washes.
Where is Wülf Wool based?
Fort Collins, Colorado. We're locally owned, every order ships from Fort Collins, and every US order ships free.
What does 17.5 micron mean?
It's the average diameter of the wool fibers, in thousandths of a millimeter. Finer fibers feel softer; at 17.5 microns, ours is soft enough for bare skin.
How do I wash it?
Wash cold with like colors and natural fabrics, then dry flat in the shade. No bleach, no tumble dry.
