Beta SL Jacket Women's is a light, packable shell jacket designed for hiking and trail use, built as a waterproof shell that provides windproof, breathable protection. Product Type: Women’s light, packable shell jacket. Material: GORE-TEX (Waterproof). Next-generation GORE-TEX ePE membrane is light, thin, strong, and PFC-free. C-KNIT backer technology improves comfort and breathability. Helmet-compatible StormHood, pit zips for ventilation, and a RECCO reflector for search situations. Pair it with women’s hiking pants and a beanie for hiking and trail days in wet, windy conditions. Made for alpine travel and mountain realities, the Beta SL Jacket – our lightest Beta – is carefully designed to deliver complete waterproof, windproof, breathable protection without sacrificing features or packability. Its next-generation GORETEX ePE membrane is light, thin, strong, and PFC free. C-KNIT backer technology improves comfort and breathability. The helmet-compatible StormHood protects without compromising vision, pit zippers ventilate, and a RECCO reflector can aid in search situations. This product is free of intentionally added PFAS. The new ePE membrane technology is lighter and thinner, but just as strong and durable as the materials we used before. You may notice the face fabric “wetting out” slightly faster in products with ePE membranes, but rest assured this does not affect the waterproofing of the membrane itself. If you notice the fabric wetting out faster than you’d like, simply wash the jacket and dry it to remove the oil contamination and bring the DWR back to its full power.
