This model is a lighter version of the famous Atom, designed to accompany you on outings in cool, changeable, or wet conditions. Its Coreloft™ Stretch insulation concentrated in the chest area provides just the right amount of warmth without compromising freedom of movement, while the uninsulated sleeves and hood improve compressibility and comfort when moving. Breathable, moisture-resistant, and comfortable to wear even over long distances, it makes an ideal midlayer, especially under a waterproof shell in the mountains.

A modernized construction for increased comfort and reduced impact

This revised version features recycled Fortius™ Air 20 fabric, which is more breathable and even more flexible, offering you unparalleled comfort during your climbs or fast-paced runs. Octa® fleece side panels optimize heat dissipation while limiting the dispersion of microfibers into the environment.The PFAS-free DWR FC0 finish provides durable water repellency, and the StormHood™, now lined, offers greater stability in the wind. Every detail contributes to a more durable, comfortable, and environmentally friendly jacket.
