A pinnacle apparel collection geared for the gruelling UTMB Mont-Blanc, our World Series capsule cues up featherweight materials that layer easily and pack in a pinch. Designed for breathable, moisture-wicking warmth, the Flight Leg Sleeves enlist corespun merino jersey, mesh panels behind the knees, and grippy silicone elastic to stay put. Worn in lieu of full trousers, these articulated leg sleeves offer enhanced visibility via reflective logos. Colour: black
