Japanese designer Junichi Abe lent his signature, meticulous approach to adidas for a Fall/Winter ’15 collaboration on a line of performance wear entitled adidas x kolor. “I greatly considered the balance between the elements of fashion and of active-wear,” he tells The Window. The collection features high-end fabrics like Climaheat and Climachill—breakthrough technologies created especially for athletes that are engineered to regulate body temperature for optimum athletic performance. “I worked closely with adidas on how to use technology-driven fabrics without affecting the overall design; instead, we carefully ensured that the design didn’t disturb the technology.”

In everything he does, Mr. Abe strives for balance. The designer, who helped launch Junya Wantanabe and Comme des Garçons, launched kolor in 2004. His designs feature unexpected fabrications in interesting silhouettes to create pieces with distinct character. “I put emphasis on expressing a nuance or mood that is relevant. I look for the point where each and every element is in balance and comes into one’s mind naturally and smoothly,” he says of his unwavering approach. “Though, I think that sometimes an unstable tension or strangeness can still attract people when it achieves its own sense of balance.”

The collaboration between adidas and kolor perfectly captures how fashion and performance wear can elevate each other to create a lifestyle. The identity of the two brands remains strong, with the silhouettes and textures—like the puckering side-seams and the rounded shape of down jacket—closely reflecting kolor’s signatures, while fully embracing the high-level technology adidas is famous for.
