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
