Our men’s trousers are engineered to strike the ideal balance between comfort and performance. Take the Gamma Trouser — made with a breathable, weather-resistant softshell — perfect for dynamic mountain environments.

Hiking trousers vary widely — even within a brand like Arc’teryx. We make everything from lightweight hiking trousers to weatherproof options and insulated designs suited for snow and cold. The Gamma Trouser remains a favourite: originally developed for alpine climbing, now recognised as a versatile, go-anywhere essential. The Beta AR Trouser is purpose-built for technical terrain and rapidly changing weather. It offers full weather protection — waterproof, windproof and breathable — in a hardwearing, articulated design. Then there’s the Proton Trouser: warm, lightweight and highly breathable, it transitions effortlessly from trail to town. With stretch comfort and full mountain versatility, these trousers work as a winter midlayer or on their own when joggers aren’t enough.

THEY’RE HIKING TROUSERS — NOT JUST ‘OUTDOOR TROUSERS’

Call them what you like — waterproof trousers, insulated trousers, technical trousers — but what matters is how they perform. Joggers and chinos have their place, but not on rugged trails or in wild weather. Hiking trousers are built for the outdoors, full stop.

BUILT WITH THE BEST MATERIALS

Technical trousers require technical fabrics. Unlike chinos, joggers, or even snow gear, our hiking trousers are made to handle whatever the weather throws your way — wind, rain, cold or all three. We use materials like Fortius™, GORE-TEX, and an extensive list of bluesign®-approved textiles — selected for performance, then precisely tailored for purpose.

DESIGNED FOR COMFORT IN MOTION

Every pair of Arc’teryx men’s trousers is built for comfort — not just in how they feel, but in how they move. Chinos and joggers might be fine for the pub, but out in the elements they fall short. If you want trousers that perform outdoors, look for technical cuts, stretch comfort, and materials that work as hard as you do.
