The Arc'teryx LEAF Fusion Jacket is a fully insulated, windproof and weather-resistant cold-weather layer engineered for operational use in harsh environments. It combines a WINDSTOPPER® outer shell with proprietary ThermaTek™ synthetic insulation, delivering a high warmth-to-weight ratio, strong breathability, and reliable thermal performance in wet or cold conditions.
The insulation uses hydrophobic polyester fibres that retain warmth when damp, dry quickly, and resist water absorption, maintaining loft and performance after repeated compression. The construction is non-quilted and laminated to eliminate cold spots and improve durability.
Designed for efficiency and packability, the jacket is lightweight and easily compressible while rebounding to full loft after storage. A high collar and stretch cuffs help retain core heat, and low-noise corded zipper pulls support discreet use in operational environments.
