A pinnacle apparel collection geared for the grueling UTMB Mont-Blanc, our World Series capsule cues up featherweight materials that layer easily and pack in a pinch. Designed in accordance with UTMB’s athlete kit requirements, the Ultralight Waterproof Pant is engineered to be as light and packable as humanly possible. Crafted from ultra-quiet Pertex®, this fully taped pant enlists articulated knees for maximum movement, a bungee waistband, and packable back pocket with elastic knuckle grab.
