When it comes to performance, we take our cues from Mother Nature. From wool that evolved to protect sheep from extreme conditions to fluffy yet durable cotton, natural fibers are inherently engineered for endurance and an essential part of the runner’s winter wardrobe.

The Magic of Merino

Let us evangelize Merino (again.) This lightweight yet warm, soft, and thermoregulating fabric is ideal for cold-weather running where you start cold and warm up along the way. Merino wards off that icy feeling of not-yet-dried sweat and resists odors so you can re-wear the same top multiple times during the week.

We’ve stood behind cotton since our launch in 2014. A soft, breathable fabric that only gets better with age, it’s our go-to material for easy days and temperate weather. Our signature Grayboy Tees – named for the ones handed out at Georgetown – are made in the USA from durable cotton jersey.

Naturally Luxurious

Who says cashmere’s not a performance fabric? This ultra-fine wool originated from hardy goats surviving on the Eurasian steppe. Blended with a touch of polyester, our waffle-knit cashmere styles balance the fiber’s signature softness with the durability needed for logging mileage.
