Light by Design

The Arc’teryx Alpha FL is a great deal of thought goes into each design element to achieve a balance between function, fit and performance. The Arc’teryx Alpha FL is designed for fast and light travel: maximum breath-ability, minimum weight. Simple, with only a single pocket, an ergonomic pattern and trim fit keeps the jacket lean.

Light by Materials

GORE-TEX® Active is the lightest, most breathable of the GORE-TEX® technologies, engineered to be worn during high output activity. Reinforced through the shoulders and hip areas with more durable N40p-X Active, the main body of the Arc’teryx Alpha FL uses a lighter weight textile.

Light by Construction

Arc’teryx uses tiny seam tape and micro seam allowances in its waterproof/breathable constructions to reduce the weight of materials, increase breath-ability and create supple, free moving garments. The elimination of zipper flaps and pit zips saves additional weight.

The Fast and Light Arc’teryx Alpha FL Men’s Jacket

Fast and light mountain travel is all about traveling light: essentials only, constant motion, energy efficient layers. Companion pieces to the Arc’teryx Alpha FL would include the Alpha SL Pant or Gamma SL Hybrid Pant and Phase base layers.
