Goldwin’s Autumn/Winter 2025 Downwear Collection Features Pre-dyed Yarns to Reduce Environmental Impact

From the 2025 Autumn/Winter season, technical apparel brand Goldwin—embodying Japanese aesthetics—presents the lightweight, highly insulating ‘PERTEX QUANTUM Down Parka’ and the ‘Dope Dyed Ripple Nylon Down Jacket’, crafted from nylon fabric offering a unique visual appeal. Both garments incorporate Kawada Feather’s ‘CLEAN DOWN’ and feature Goldwin’s proprietary baffle construction for efficient core warmth.

Here’s a bit of trivia. Feathers harvested from waterfowl retain dirt, dust, grime, and oils. Only after undergoing a refining process involving dust removal, washing, and drying can they become usable as down insulation. Residual impurities in feathers cause unpleasant odours and trigger allergies.

The more thoroughly the down is cleaned and refined, the longer it retains its loft. It is no exaggeration to say this refining process is the decisive factor in determining down quality. Recognised as world-leading in this technical expertise is Kawada Feather, the largest among Japan’s scarce domestic feather suppliers. Its headquarters and factory are located along Ise Bay in Mie Prefecture, which uniquely combines ultra-soft water – highly effective for feather refining – with a dry climate.

The fine-grained, ultra-soft water, free from dissolved minerals, possesses high permeation power. This effectively removes dirt from every corner of the feathers while minimising detergent usage. Years of research in this environment have borne fruit, and Kawada Feather’s current feather cleaning precision achieves values exceeding the quality standards set by the Japan Feather Products Cooperative Association. Beyond this “CLEAN DOWN”, the brand’s material selection is packed with sustainable considerations, including lightweight Pertex Quantum and eco-friendly yarns dyed in the mass.
