Heeju Park is director of the Performance Apparel Design Lab. His team has developed protective ice hockey padding specifically for women, using 3D body‑scanning to better fit female athletes and reduce soft‑tissue injuries. He previously served as an athletic apparel and footwear manager at PUMA Korea.

 Park says about Team USA’s Nike Therma‑FIT Air Milano Jacket:

• “Nike’s thermal-regulation approach based on inflation and deflation is an excellent way to make athletes’ outfits lighter and more comfortable. The thermal conductivity of air is greater than any textile material. Still air contained inside a windproof and waterproof textile is the most effective and the lightest thermal insulation. This approach also protects athletes from windchill.”
