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.

Features

Certified non-mulesing wool
Note: due to the open knit structure of the fabric, hydration packs may cause pilling
Weight: 98 g (size M)
Regular fit
18.5 micron superfine merino wool

Fabric & Care

Merino wool is naturally antibacterial so you won't have to wash after every run.

- Wash inside out to avoid pilling on a delicate cycle
- Wash in cold water with a mild detergent
- Lay flat or hang to dry

63% Merino Wool, 29% Polyester, 8% Nylon

Top tier shirt for getting after it in my training. Running, lifting…I was dry. Hung dry and the following day it smelled like new!

Literally the lightest shirt I've ever experienced. Keeps you cool when running and they've thought of everything: no seams rubbing in weird places, the cut and fit is stellar. Can't recommend enough!

Everything is dialed on the Courser Tee from the fit and feel to the performance. Works incredibly well in the summer humidity and I’m looking forward to wearing this as a layer into the fall months as well. Started with two tees and ended up ordering another within days of my first order. Excited to see what comes next!

This Tshirt is amazingly comfortable and the perfect addition to any runners life.

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.

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!
