Arc'Teryx Men's Alpha SL Jacket Black - XL

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.
