Mammut

Aenergy IN Vest - Men's

When you're heading out on demanding ski tours and quick-moving alpine expeditions, you want insulation that can breathe, and now you've got it thanks to the Mammut Aenergy IN Vest. This vest was designed with Polartec Alpha Direct insulation, an innovative fabric that places its soft insulating material directly next-to-skin to save weight and maximize comfort, while giving you the reliable temperature-regulating breathability that you need when you're working hard in cold weather. The Pertex Quantum Air shell provides wind and water resistance, so you can rock it as an outer layer on warmer tours, while the back panel features a stretchy and quick-drying fleece material for easier movement and greater overall comfort. You've got a partially elasticized hem to seal in your warmth, and when your journey is over and done with you can stuff the Aenergy into its own side pocket and throw it back into your pack.
