Mammut Aenergy Wb Hooded Jacket - Men's

Product Insights & Style Tips

Take the edge off the windchill with a lean, technical windbreaker. Mammut Aenergy Wb Hooded Jacket keeps the chill at bay without weighing you down. The face fabric is 100 percent recycled nylon with a PFC-free DWR, while inserts are 83 percent nylon and 17 percent spandex for durable stretch. A helmet-compatible hood and a two-way zipper keep the silhouette clean, and the secure chest pocket moonlights as a stuff bag when the layer isn’t in use.

With a regular hip-length profile, it layers over a base or fleece and under a shell as conditions shift. The two-way zipper vents when you heat up on a climb, and the durable stretch forearms move with you through grip, reach, and rope work. The chest pocket secures small essentials and doubles as a pack-able sack, so the jacket compresses down neatly when you shed it. Breathable and lightweight, it stays comfortable from belay to breeze.

Mammut leans into the edge of performance with pared-back, packable outerwear. The Aenergy Wb Hooded Jacket sits at that sweet spot between rugged utility and light-as-air layering, underpinned by bluesign approved fabric and recycled materials that align with today’s sustainability-minded outdoor codes.
