The long-sleeved X-Alp Performance Wool 115 Trail Running Shirt is a running shirt like no other: it is lighter, more durable, and dries faster than conventional merino clothing. This stylish striped shirt features thumb loops and is made from performance wool developed by Nuyarn – a wool blend that offers very similar performance characteristics to wool. Naturally temperature-regulating, it cools when it's warm and warms when it's cold. Additionally, it is naturally antimicrobial, meaning it is odor-resistant. The functional material made from mulesing-free merino wool dries five times faster than regular merino clothing – perfect for longer trail runs and ideal under a vest or jacket. Enjoy lightweight and high-performance wool – so natural that you won't want to wear anything else.
