Mammut’s Aenergy ML Hybrid Vest Women targets ski touring and mountain ascents where heat management matters. Its body-mapped construction combines Polartec Alpha Direct with wind-breaking nylon across the front and collar.
The lining-free insulation is designed to retain warmth while allowing excess heat and moisture to escape. Stretchy double-weave nylon inserts support movement, helping the vest work as part of an active layering system.
Two front pockets are arranged for access when wearing a climbing harness. Mammut lists a regular fit and a weight of just 140g. The main material is recycled polyamide, and the vest carries bluesign PRODUCT, Fair Wear and PFC-free DWR designations. It is a lightweight option for users seeking warmth around the torso during sustained uphill activity.
