The Cascade LS by Mons Royale in the fitted version is a particularly stretchy long-sleeve shirt made from merino wool with polyamide content. The 200 quality shirt also has a slim fit and can therefore fully fulfill its functions: Wicking away moisture, keeping you warm or letting off steam and inhibiting the build-up of odors. It has a round neckline and raglan sleeves with thumb holes to keep your hands warm too.
