It features a hybrid of KODENSHI® down and high-quality down (manufactured by Kawada Feather Co., Ltd., etc.), resulting in a lightweight jacket with excellent heat retention and functionality.

It pursues comfort in outdoor scenes such as fishing and is characterized by its versatility, making it suitable as both an outer and inner layer. Key Features: KODENSHI® material: This material absorbs and radiates far-infrared rays emitted from the body, warming the body from the core, and exhibiting excellent heat retention and quick-drying properties. High-quality down: Uses high-quality down (feathers) that meets strict standards, twice as stringent as domestic standards, achieving high heat retention while being lightweight. Hybrid structure: Combines down and KODENSHI® material, with water-repellent KODENSHI® down used for the body and KODENSHI® knit for the sleeves and underarms, optimizing material placement for each area. Lightweight and compact: Extremely lightweight. Fishing-specific functions: Equipped with numerous functions to enhance comfort in fishing environments, such as wind resistance, stretchability, water repellency, and anti-static function (static-dissipating fiber). Uses: As an outer or mid-layer in harsh cold field conditions. Designed for everyday use in town. As an inner down layer in extremely cold regions. The Free Knot down jacket is not just a cold-weather garment but is supported by outdoor enthusiasts and anglers as "plus-one" functional wear that integrates various features.
