Arc'teryx Men's Alpha SL Jacket

  • $279


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/breathable protection for sudden storms. By putting intense focus on design, fabric and feature selection, Arc’teryx designers held the weight at 305g (10.8 oz), and allowed the jacket to easily pack into its own hood or included stuff sack.

MOST PACKABLE

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.

EVERYTHING ESSENTIAL

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.

The Arc'teryx helmet compatible Stormhood is designed to provide the ultimate protection in cold or wet weather. The laminated brim and hood adjusters secure tightly and deliver full coverage without restricting movement or visibility.

  • Laminated brim
  • Adjustable hood cinch cords
  • Tall collar for full coverage

The Arc'teryx Harness HemLock insert is designed to keep your jacket from riding up when wearing a climbing harness. The foam insert can be removed when not needed.

  • Lightweight
  • Functional — keeps jacket in place when worn under a climbing harness
  • Removable
