5 TRENDS IN THE RUNNING HARD-CORE FABRIC PERFORMANCE THAT'S EASY ON THE EARTH. BY EMILY WALZER adidas Training Techfit Control apparel featuring Rheon Labs film technology 6 • November/December 2023 sportstyle • sportstylemag.com The focus of material innovation for active sportswear has long been driven by developing textiles to help athletes perform like well-oiled machines, training efficiently and competing at their best. Now however, high-tech functionality also meets eco-friendly standards, giving way to a new class of fabrications that are advantageous both to the individual and the environment. Here's a quick rundown of five key textile trends influencing the future of running apparel and footwear: Trend #1: Strides in Performance Rheon Labs reactivewear relies on RHEON film technology that is strategically placed in garments across major muscles, or so tissue, adapting to movement to provide support. Director of apparel Simon Huntsman explains that the material stiffens during high-intensity movements, and soens during lower-impact motion. In running tights for example, the inherent dynamic properties help control muscle shearing (muscles moving out of plane) by responding with tension when subjected to force providing runners enhanced efficiency. When used in a sports bra application, RHEON film provides the primary support mechanism, thus reducing the need for high compression, which is oen associated with discomfort. Polartec Delta fabric combines a unique fabric construction and fiber blend to raise the bar in keeping runners cool in the heat and comfortable in cool conditions. e technical knit fabric is a blend of polyester and Tencel fibers that work in concert to take moisture off the body quickly for rapid drying. Delta fabric also features increased airflow with its distinct raised texture. "It feels like it floats on top of your skin," states Polartec's product development manager Aimee LaValley who runs in Delta tops year-round. DESIGN
