Cold mornings. Early hikes. Icy commutes. The Glacier Glow Insulated Jacket Men by Mammut is the insulated jacket that brings high alpine warmth to everyday life. Engineered with serious mountain performance in mind and designed for versatility, this is your go-to layer for warmth in winter conditions—on trail or in town. At its core is high-quality recycled down with 700 cuin fill power, wrapped in a windproof recycled polyamide shell. A PFC-free DWR treatment offers reliable water resistance for snow flurries or light rain, while oversized down chambers maximize heat retention without unnecessary bulk. From frozen urban sidewalks to quiet snow-covered paths, this jacket delivers comfort where it counts. More than just a hiking jacket, the Glacier Glow Insulated is part of Mammut's commitment to sustainability and ethical production. As a proud Fair Wear member, Mammut ensures safe working conditions and responsible sourcing across 97% of its supply chain. Inspired by the Swiss Alps and built for performance, Mammut gear is designed to endure—and protect what we love most: nature. Wear it over a base layer or mid-layer, or under a hardshell for extra warmth when conditions demand more. Lightweight, technical, and consciously made—this is an insulated jacket mens collection can rely on, season after season.
