Mammut Aenergy IN Hybrid Jacket Men Jacket

The Aenergy IN Hybrid Jacket Men from Mammut is a lightweight, hoodless insulated hybrid jacket for active cold‑weather use. It pairs Octa® Loft synthetic insulation with breathable stretch fleece panels to balance warmth and moisture management during high‑output efforts.

Key benefits

• Hybrid construction: synthetic insulation in core areas and elastic waffle‑fleece panels in high‑movement zones for improved temperature control.
• Octa® Loft contains partially recycled content (52%) and retains insulation when damp.
• Light insulation (87 g/m²) with low pack volume and easy compressibility.
• Wind‑resistant face on insulated sections reduces drafts.
• Two zippered hand pockets and packable into the left pocket for convenient transport.

Designed for high‑output mountain activities such as ski touring, fast hiking and other aerobic alpine efforts in cool conditions where a balance of warmth and breathability is required.
