Best Merino Running Shirt
Black Diamond Rhythm Tee
The Black Diamond Rhythm Tee is a well-regarded option that combines the performance properties of natural and synthetic materials. It’s made from NuYarn, where wool fibers are spun around a core of nylon. The result is a fabric with the breathability and temperature regulation of merino and the stretchiness and durability of nylon. It’s also lighter and dries faster than your typical merino garment. One caveat: Some reviewers have had issues with this shirt pilling. Overall, it’s a versatile option you can wear in a variety of scenarios. It’s an especially good pick for running in chillier weather.
