Arc'teryx Proton Hoody Men's Carob

The Arc'teryx Proton Hoody is a benchmark in breathable insulation. Created for mountain athletes and everyday adventurers, it balances warmth, airflow, and freedom of movement like no other. Whether you are hiking, ski touring, or climbing, the Proton Hoody delivers comfort that adapts to your pace and environment.

At its core lies Fortius Air 20, a lightweight yet exceptionally durable fabric that allows air to flow while protecting against wind and abrasion. This balance ensures you stay dry and comfortable even during intense activity. The fabric’s soft hand feel and quiet performance enhance both function and wearability.

Inside, Coreloft Compact insulation provides consistent warmth that continues to perform when damp. This advanced synthetic fill is engineered to resist packing out over time, maintaining loft and thermal efficiency season after season. It offers the warmth of traditional insulation without the bulk, making it ideal for layering or wearing on its own.

The athletic fit and articulated patterning follow the body’s natural movement, giving complete freedom whether you are on steep ascents or managing transitions in variable weather. The helmet-compatible StormHood offers low-profile coverage with excellent peripheral vision, while adjustable hem and cuffs help seal in warmth without restricting motion.

A PFC-free durable water-repellent finish adds protection from light snow or drizzle, extending the Proton’s range into unpredictable conditions. Designed to function both as a standalone outer layer and as an active mid-layer under a shell, it brings versatility to every season and setting.

Built for longevity, the Proton Hoody’s abrasion resistance and technical construction mean it can withstand years of demanding use in the alpine, backcountry, or urban landscape. It is the go-to choice for those who want dependable warmth that keeps pace with their energy.
