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 for breathable, moisture-wicking warmth, the Merino Tight enlists mesh panels in high-sweat zones and an elastic waistband with integrated drawcord. A fitted style with thigh pocket for on-the-go nutrition, this ultralight base layer packs down snugly into the back panel.
