Super-light Packability

The women's Alpha SL Jacket is a super-light shell constructed using N40r GORE-TEX® fabric with PacLite® technology. This combination results in one of Arc'teryx most packable, waterproof, and breathable fabrics that remains durable enough to wear climbing and hiking. It also utilizes 1.6 mm micro-seam allowance to reduce bulk without sacrificing strength, while GORE® seam tape improves its weatherproof seal. It's patterned using e3D technology for a trim, clean, activity friendly fit and been designed with only essential features, keeping its weight to a measly 365-grams. The Alpha SL is an ideal companion on Rocky Mountain climbing trips and day treks around eastern Canada's National Parks.
