Long Down Jacket

Nowadays, consumers are asking for long down jackets featuring a light weight, wearing comfort, freedom of movement, and all-scenario adaptability instead of those only with heat retention. Considering that, this product, centered around the idea of ‘movable duvet’, makes systematic innovations in structural design and material selection, achieving a harmonious unity of heat retention, freedom of movement, and practical functionality.
This down jacket innovates a 3D anti-down-leakage system: the 50D ultra-fine polyester fabric as the outer layer, coupled with the high-density down-proof inner layer and advanced 3D stitching technology, effectively prevents down from coming out, achieving a down leakage rate lower than the industry average of 8%. At the same time, the silver-ion heat-retaining lining—commonly used in professional outdoor gear—boasts a far-infrared emissivity of 0.90, which can absorb and reflect the body’s infrared heat to create a dynamic heat-retaining layer. It efficiently maintains dynamic thermal balance in -15°C-5°C environments, enabling consistent comfort during indoor-outdoor shifts. In terms of silhouette design, the scientifically engineered front panel (with a 165.5° shoulder slope) and rear panel (with a 171.5° shoulder slope), complemented by an optimized armhole structure, offer a perfect fit during upper-body movement. This addresses the hassle of exposed wrists when raising arms common in traditional long down jackets, significantly enhancing freedom of movement. In addition, the oil-resistant fabric applied to the collar allows stains to be wiped away easily, facilitating convenient daily maintenance.
To balance exceptional heat retention and a light weight, the product employs the 650+ FP duck down and the 73g/m² 50D ultra-fine polyester fabric. In this way, it keeps its weight at just 1.25kg, with its size reduced by 1/3 after compression, ensuring not only a light wearing experience but also excellent convenience for storage and carrying.
