Lightweight construction creates a packable jacket that is capable of attacking fast and light alpine ascents without sacrificing weather protection.


Beta LT’s older sister—Beta AR—has been in the Arc'teryx lineup since 2000. That kind of mountain heritage brings credibility and with this ultra lightweight version, increases your speed uphill. 


Highly breathable GORE-TEX® Pro synchronizes comfort with performance. The micro grid backer and a premium quality face fabric keep the jacket lightweight and supple, yet fully capable in the worst storm conditions.


Put your head down, get into a rhythm, and forget about your gear. A trim fit increases breathability by keeping the jacket close to your body, to transfer moisture vapour rapidly on high output days.
