What Our Gearhead(R) Experts Are Saying:"I packed this for an exposed alpine route and pulled it out the moment the wind picked up on the ridge. The body-mapped panels kept me cool through the technical sections while the front and hood blocked the worst of the gusts."Wind can turn a good climb into a miserable one fast, and Mammut built the Aenergy WB Hooded Jacket to shut that possibility down. The Pertex(R) Quantum Air fabric blocks windchill across the front, back, and hood, while a softer, stretchier version at the underarms and sides keeps you cool and mobile through technical moves. Body-mapped construction means the jacket works with you, not against you, whether you're pushing through an exposed ridge or grinding out the final miles of a trail run. A PFC-free DWR coating sheds light moisture, and recycled fabric throughout keeps the build environmentally conscious without sacrificing performance. When the wind dies down, the jacket packs into its own chest pocket, ready to disappear until you need it again.
