What Our Gearhead® Experts Are Saying:

"This is my go-to jacket for high-output activities in cold conditions. The Octa® Loft insulation keeps me warm without overheating, even when I’m working hard on the ascent. I love how breathable and stretchy the hybrid design is—it moves with me while blocking wind where I need it most. Plus, the pockets are harness-compatible, and the jacket stuffs into its own pocket, making it easy to stash in my pack."

The Mammut Aenergy IN Hybrid Jacket is built for high-energy pursuits in cold conditions. Designed to balance warmth, breathability, and mobility, this lightweight layer keeps us comfortable through varying temperatures without constant layering adjustments. The strategic hybrid construction pairs wind-resistant fabric with stretchy storm fleece panels, ensuring freedom of movement where we need it most.
