Women's Courser Tee
Ultralight performance merino for summer conditions. Breathable, quick drying, and odor resistant.
We built the Courser Tee for your daily trail miles in hot and variable conditions. Built with MirageWool™, our ultra-lightweight 115 GSM merino blend with Nuyarn technology, it brings forward the best performance attributes of merino wool in a fabric tailor made for days on the trail.
Featuring an open-knit structure, the Courser Tee actively breathes and manages moisture by pulling sweat away from your skin before you even feel wet. MirageWool™ doesn’t cling when saturated, maintaining a light, airy feel throughout an effort.

I LOVE these shirts! I got two t-shits and a tank. They are lightweight, fast-drying, and stink-resistant. The cut fits nicely, not too tight or bulky. I can wear it multiple days in a row and use it for running or as casual wear. It would be great for multi day backpacking. Really nice natural colors. 11/10 recommend purchasing this product.
I received my tee a couple of days ago and absolutely love it. I’m retired now and live in running clothes- living in Florida- this tee is the most breathable, comfortable and activity worthy top I own…. It holds up well with the heat and humidity and is so soft (and it fits great and is pretty!). Unknown Runner knows what they are doing!
I am getting one in every color- and as a plus, it can definitely be worn as non-athletic wear! Incredible fabric and colors. Thank you!
I was excited to try out the brand, but didn't know what to expect... When I took this tee out of the package, I yelled out to my husband, "oh my gosh, these are NICE!" The fabric is actually incredible, and the fit is perfect. Shoulders are exactly where they should be, and we all know that's rare for a women's tee. It's fitted without being tight, and SO lightweight. Can't wait to place my next order.
Super lightweight, great fit, breathable. Went with a size medium to a looser fit. 5'3 and 135#. Great for running and hiking but styling enough to wear all the time. It really doesnt smell after a hard effort.
10/10 purchase <3
Super comfortable and lightweight, especially for a wool shirt! Ran in CO in the summer heat in it and felt amazing, and using for a sleeping baselayer on a backpacking trip in Peru!
