SHORT DESCRIPTION

This lightweight long down jacket, centered around the idea of ‘movable duvet’, aims to fully optimize its wearing comfort, freedom of movement, and multi-scenario adaptability while delivering exceptional heat retention. The product 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 mountaineering gear—boasts a far-infrared emissivity of 0.90, which can efficiently absorb and reflect the body’s infrared heat to create a dynamic heat-retaining layer, effortlessly tackling indoor-outdoor shifts. In terms of silhouette design, the precisely 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. Additionally, 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 down jacket employs the 650+ FP duck down and the 73g/m² 50D ultra-fine polyester fabric. Thanks to such an optimized material combination, it greatly improves heat retention and keeps its weight at just 1.25kg, with its size reduced by 1/3 after compression, ensuring both a light wearing experience and high portability.
