Let customers speak for us
Light weight and comfortable. And earth colors are great for hunting.
Love this shirt. Light, dries fast, comfortable, and cute. I don’t run but wear it for sand volleyball and it’s the perfect shirt for that!
This Tshirt is amazingly comfortable and the perfect addition to any runners life.
Easy order, fast shipping. Even got a hand written note in my order. Thanks Unknown Runner!
Great piece of kit. The shirt is super comfortable and breathable. Absolutely no smell after running three times without washing. Just hang it up to dry and put it on the next day!
Awesome shirt. Worn it twice now and it’s great. Super breathable and cool, even in the hot summer.
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.
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!
Understated and high performing. My first runs with the courser tee were in the Sierra, quickly followed by coastal Alaska. It performed amazingly well in both.
Every time I put it on, I’m impressed with its versatility and comfort. Unlike most running tees, this one stands off the skin and doesn’t cling when wet. Can’t wait to fill my closet with more.
I bought this shirt at TrailCon a few days ago. TrailCon is a trail running conference with most of the brands in trail running, big and small. I looked at everything available and this shirt was the only piece of gear that I bought. I’ve been running for a long time and I have a lot of gear already. I would have been happy to keep my wallet in my pocket, but this shirt is something special and I had to have it.
It is so light and comfy while built with craftsmanship that makes me think it will last a long time.
I wore it all day yesterday, then slept in it, and then raced in it today. It was perfect for all of those moments. I’ve rinsed it in the sink and hung it to dry and I’m excited to put it on again soon!
Absolutely fabulous tee shirt. It’s definitely “performance” wear but I like being able to wear it when running errands or just being outside in the Texas summer. It handles sweat very well. The fit and feel is excellent; people ask me where I got it. I’m very curious to see what else this label releases. Onward!
