Description
Description
The Aenergy ML Hybrid Vest combines Polartec® Alpha® Direct insulation with a smart hybrid construction to keep you warm without overheating. This lining-free fabric traps body heat during high-output climbs and ski tours while venting excess moisture the moment you slow down, making it a genuine one-piece solution for variable alpine conditions. Wind-resistant nylon panels across the front and collar shield your core from cutting winds on exposed ridgelines and summit pushes, while stretchy double-weave nylon inserts at the back and sides boost breathability and freedom of movement.
Weighing in at just 160g, the Aenergy ML Hybrid Vest is a featherweight addition to any technical layering system. A regular fit allows for easy layering over base layers or under a hardshell, while two climbing-harness-compatible front pockets with cross-over access let you stash essentials like snacks, a compass, or gloves without breaking stride. The lining-free Polartec® Alpha® Direct insulation delivers exceptional heat retention while eliminating the clammy heat build-up associated with traditional synthetic fills. Compact, packable, and built to move with you, this vest is a must-have for alpinists, ski tourers, and fastpackers who demand performance-driven gear that punches well above its weight.
