The Cascade leggings from Mons Royale are made from a particularly stretchy merino blend fabric with plenty of merino wool, polyamide and elastane and are a classic basic. They fit snugly and have a wide and comfortable elasticated waistband with logo lettering. And because the leggings are made from merino wool, they can: Wick away moisture, regulate temperature, keep you warm even when damp, inhibit the build-up of odors while remaining soft and unscratchy against the skin.
