The Arc’teryx Beta SL Jacket is a lightweight, packable waterproof shell designed for mountain weather, trail use, and everyday outdoor protection. Built with 3-layer GORE-TEX ePE fabric and a soft C-KNIT backer, it delivers fully waterproof, windproof, and breathable performance while remaining comfortable during high-output activity. Designed as the lightest jacket in the Beta series, the Beta SL balances durability, weather protection, and packability, making it a reliable outer layer for hiking, running, travel, and changing conditions.
A helmet-compatible StormHood™ provides full coverage without blocking vision, while pit zips allow quick ventilation when the pace increases. The articulated fit, lightweight construction, and adjustable hem and cuffs make the jacket easy to layer over midlayers without restricting movement. Built for versatility across a wide range of conditions, the Beta SL is ideal for anyone who needs dependable waterproof protection without carrying extra weight.
