Ultralight warmth and breathability in the Aenergy Light ML Hooded Jacket
What Our Gearhead® Experts Are Saying:
"I grab the Aenergy Light ML Hooded Jacket when I want just enough warmth without sacrificing breathability. It works perfectly as a base layer on cold tours or as a midlayer when I’m moving fast. The hood fits cleanly under a helmet, and it dries incredibly fast after hard efforts."
We rely on the Aenergy Light ML Hooded Jacket from Mammut when efficiency matters most. It’s our go-to layer for early-morning ski tours, fast alpine missions, and summer hikes where weight, breathability, and versatility make all the difference.
Built with Polartec Power Grid fleece, this ultra-light midlayer delivers exceptional warmth for its weight while wicking moisture quickly during high-output movement. The athletic fit layers easily, and the snug hood fits comfortably under a helmet for added coverage when conditions change. Flatlock seams reduce friction, and a laminated chest pocket provides streamlined storage without bulk, making this piece a reliable companion across seasons.
