Designed for ultimate freedom of movement and mobility, the Rhythm Tee with its NuYarn merino technology is significantly lighter than other wool shirts on the market and at the same time superior in terms of its performance. The Rhythm's NuYarn fabric dries 5 times faster than regular merino and has 35% more stretch. For this reason, the Rhythm Tee offers the ultimate and extremely breathable layer for sporting activities or mountain running.
