The Arc’teryx Beta SL Jacket is a lightweight, packable waterproof shell designed for mountain travel, hiking, and everyday outdoor use in unpredictable weather. Built with next-generation 3-layer GORE-TEX ePE fabric and a soft C-KNIT backer, it delivers full waterproof, windproof, and breathable protection while remaining comfortable during high-output activity. As the lightest jacket in the Beta range, the Beta SL balances durability, weather resistance, and packability for versatile use across a wide range of conditions.
A helmet-compatible StormHood™ provides full coverage without restricting vision, while pit zips allow fast ventilation when the pace increases. Articulated patterning ensures unrestricted movement, and the lightweight construction makes the jacket easy to carry when not in use. Designed for alpine environments but equally suited to travel and daily wear, the Beta SL is built for reliable protection without unnecessary weight.
