Ultralight Down 3-in-1 StormJacket

Rooted in the practical needs of cross-scene autumn and winter dressing, this product embodies the philosophy of "One Garment, Urban to Outdoor," offering an efficient transitional aesthetic. It breaks boundaries between workplace occasions and light outdoor activities, allowing users to maintain both appropriateness and ease while achieving fluid adaptation across different settings.

The design centers on "AIRWARM+" lightweight intelligent warming technology. The outer storm jacket uses AAA-grade 8 denier Cordura fabric with Teflon triple-protection and a 100% PU micro-nano porous Gore membrane, delivering rainstorm-level performance with over 8,000mm hydrostatic resistance and moisture permeability. Ultrasonic cutting and seam-sealing enhance the lightweight texture, while a utility pocket on the left sleeve adds practical storage.

The inner down jacket features Japanese Toray’s ultra-light AIRTASTIC™ 10 denier fabric and Kanglun Aerospace’s AEROWARM thermal lining, which locks in heat through far-infrared heating and storage. Innovative down quilting and a no anti-velvet lining process ensure high-quality goose down retains both loft and softness. A 3-in-1 detachable structure offers three wearing options, with a unisex fit adaptable to diverse body types.

The core design challenge—balancing “lightweight” with “adaptive protection”—was addressed through careful fabric selection and testing. Down filling was reduced by 45% without sacrificing warmth, thanks to NuanYan down with micro-ceramic coating technology. Multiple prototype iterations ensured a comfortable fit whether worn separately or together.

In line with sustainable principles, the outer jacket incorporates bio-based yarns, while the inner jacket uses recycled and bio-based materials from Toray’s AIRTASTIC™ series, reducing carbon footprint and supporting eco-friendly development.

By combining lightweight materials and precise craftsmanship, the product addresses bulkiness issues in autumn and winter wear. It delivers full-scene protection—breathability, water resistance, stain resistance, and thermal retention—seamlessly adapting to workplace and outdoor transitions. The gender-neutral design and versatile 3-in-1 wearing method give users freedom of choice, ensuring comfort, protection, and warmth across diverse urban and outdoor scenarios.
