Weighing only 280 grams (9.9 oz) and highly packable, the women’s Beta SL Jacket is carefully designed to stay unnoticed until it’s needed. Intended as emergency weather protection for hikers, backpackers and trekkers, it is made from N40r GORE-TEX® fabric with Paclite® product technology for reliable, proven waterproof/breathable performance. Designed specifically for women, the patterning, built in freedom of movement and careful feature placement elevate the Beta SL’s fit and functionality.MOST PACKABLEAs weight and space are critical factors in the Beta SL’s performance, the lightest and most packable GORE-TEX® fabric, N40r GORE-TEX® fabric with Paclite® product technology, is used. Waterproof and highly breathable, the fabric protects from the weather and offers a higher level of comfort during activity. As the Beta SL is intended for periodic emergency use, a less abrasion resistant textile is used to eliminate weight and bulk. However, the fabric has a mini ripstop construction that provides added tear strength without impacting weight.SIMPLICITY IN ACTIONThe goal was to pare the Beta SL to its essence and achieve specific functional requirements for the lowest possible weight. Careful, efficient construction techniques allow Arc’teryx to use micro seam allowances and tiny (13 mm) GORE® seam tape. The Trim fit reduces fabric requirements and improves breathability. Carefully articulated patterning and gusseted underarms provide freedom of movement without adding bulk. The low profile Stormhood™ offers complete coverage with a streamlined design. This is a true minimalist’s hardshell, designed to be light, small and efficient.
