All about this product



The Men's Proton Hoody by Arc'teryx is a high-performance marvel designed to meet the ever-changing demands of mountain pursuits. This versatile hoody is a self-regulating mid-layer that excels in high-output activities. What sets it apart is its innovative breathable insulation package, which allows excess heat and moisture to escape through a combination of air-permeable fabrics and insulation. This means you can stay comfortable and dry during intense physical exertion, making it an ideal choice for those who seek peak performance in the mountains.


Arc'teryx's Proton Hoody also boasts Fortius Air 20 face fabric's remarkable durability, surpassing industry standards by over 60 times in abrasion tests. This exceptional toughness ensures that the hoody can withstand rugged mountain terrain and the wear and tear of outdoor adventures. The Coreloft Compact 80 synthetic insulation in the body offers warmth and excellent stretch recovery, allowing unrestricted movement during your activities.

About this brand

No one does mountain kit quite like the Canadian brand, Arc’Teryx, who were originally called Rock Solid. Founded in 1989 by Dave Lane, they have a long history of innovation and are loved for their minimalist style, design features and craftsmanship. Everything they do is beautifully made and thanks to the use of GORE-TEX, is fully waterproof, windproof and built to last. Arc’Teryx comes from the Archaeopteryx, one of the earliest know birds. The logo is based on the ‘Berlin specimen’, a fossil of the bird and the most complete skeleton found to date.
