The Mammut Men's Whitehorn IN Jacket is warm enough for hiking snow-covered mountains, so you know it'll be nice and toasty for the rest of winter when you're stuck in town. Its hybrid design pairs light and lofty down insulation with Anjungilak Element synthetic insulation in areas that would most likely get wet. Mammut wrapped this hybrid insulation in Pertex's Quantum fabric for windproof protection, water-resistance, and performance-oriented breathability. The Whitehorn is reversible; one side sports a modern look, while the other has a trendier retro fashion.
