1960年代からスキー人口が徐々に増え、1972年に開催された札幌オリンピックの時には日本にスキーブームが到来した。アウターウエアなどの防寒具もニットが主流だった時代から、今では当たり前となった布帛（フハク）素材へとシフトしていった。ゴールドウインもスキー用品のクオリティー向上に目を向け、1970年にフランスのフザルプ社との提携をスタート。技術を重視しているフザルプ社は世界からのアプローチが絶えなかったが、技術を守るために他社との提携を結んでいなかった。彼らの技術に魅せられた西田はフザルプ社に何度も通い、その熱意を伝えた。そしてその思いがフザルプ社に届き、ついにゴールドウインは世界初となる提携を果たした。そこから、スキーウエアの進化が加速していく。当時日本では平面裁断が一般的だったが、フザルプ社は体の曲線に合わせてカッティングを施し、立体裁断を採用していた。この方法は、体にフィットする美しいシルエットを作るために必須だった。職人たちはサンプルを分解し、最先端の技術を取得していった。研究を重ね、体の動きにフィットするスキーウエアの開発を実現した。フザルプ社の製品にかける思いとゴールドウインのものづくりの姿勢には共通点があると感じていた西田は「貴重な技術や思想を学んだ」と話している。ウエストを絞った曲線的なシルエットでありながら動きを邪魔しないデザインやパンツとジャケットをファスナーでつなげることで暖かさを維持できるワンピース型のウエア、バックリングパンツなど、機能性とデザイン性を兼ね備えたセンセーショナルな製品を次々と打ち出した。フザルプのブランドが持つ特徴をキープしつつ、日本人に合う体型や色、スタイルへとオリジナリティーもプラスしていった。さらに当時では考えられなかった、毎シーズン全品番のフルモデルチェンジや、ファッションショーの開催等、他社にはない戦略も話題を呼び、毎年注文が殺到した。

The skiing population had gradually increased since the 1960s, and when the Sapporo Olympic Games were held in 1972, a ski boom arrived in Japan. As for protection against cold such as wear and outer garments, the times changed from the age of knitwear as the mainstream to woven fabric materials, which have become common now. GOLDWIN also turned to improving the quality of skiing supplies, and entered into a partnership with Fusalp in France in 1970. Fusalp, who emphasizes the technology, had been continuously approached by companies from around the world, but did not partner with any other company to protect its technology. Nishida was fascinated by the technology of Fusalp, and made repeated visits to Fusalp to appeal his enthusiasm. His passion finally reached Fusalp and GOLDWIN became the first company in the world to join hands with Fusalp. After that, the evolution of ski wear started accelerating. In those days, a flat pattern cutting was common in Japan, but Fusalp had adopted three-dimensional cutting, which is a cutting process according to the curves of the body. This method was essential for making a beautiful silhouette that is fit to the body. The craftspeople disassembled the samples and learned the latest technology. After repeated research, the development of ski wear that fit the movement of the body was accomplished. Nishida felt there was something in common between Fusalp’s passion for products and GOLDWIN’s approach to manufacturing. He said, “I learned valuable technology and philosophy.” GOLDWIN launched sensational products one after another combining functionality and design, including the design which does not disturb movement while having a curved silhouette with a narrow waist, a one-piece type wear connecting pants and a jacket with a fastener thereby maintaining warmth, and buckling pants, etc. While keeping the characteristics of Fusalp, GOLDWIN’s originality was added, too, such as body shapes, colors and styles that matched Japanese people. Furthermore, the strategy that other companies did not have, such as full model change of the collection every season and holding fashion shows, which was unimaginable in those days also drew attentions and orders poured in every year.
