Carefully designed to be as light and packable as possible without sacrificing key elements required by alpinists and climbers, the Alpha SL delivers highly effective waterproof and breathable protection for sudden storms. By putting intense focus on design, fabric and feature selection, Arc'teryx' designers held the weight at 305 grams, and allowed the jacket to easily pack into its own hood or included stuff sack.
As weight and space are critical factors in the Alpha 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 Alpha SL is intended for periodic emergency use, a lighter less abrasion resistant face is used to eliminate weight and bulk. However, the fabric has a mini ripstop construction that provides added tear strength without impacting weight.
The Alpha SL's disciplined design is pared down to the essentials. The helmet compatible StormHood delivers full coverage with a secure fit that provides ergonomic performance and exceptional freedom of vision and Hemlock inserts help prevent the jacket from riding up under a harness. The Trim fit with motion friendly e3D patterning is designed for mobility, yet keeps the jacket close to the body to enhance breathability, reduce bulk and improve the line of sight towards a harness.

Arc'teryx challenges what exists, manufacturing new ideas is their culture. Passion and curiosity fuel a continual drive to explore, to push the boundaries of what is known, regardless of assumptions. Founded by Vancouver climbers in 1989, Arc’teryx has but one single goal; to create equipment that enables a person to be immersed in the moment of doing, regardless of external conditions.
Their Design Centre is a hive of likeminded individuals, a hands-on think tank of active designers, materials experts, pattern makers and product developers who know what they want, how it will be used and why it has to work. Arc’teryx's dedication to craftsmanship is expressed through their manufacturing processes, quality and integrity can only be achieved through effective partnership with their factories and suppliers.
Arc’teryx strive to deliver products that are as good as they can possibly be, so that they perform over time and beyond expectation, this is the heart of what Arc'teryx does and the roots of the company — to create what does not yet exist.
