HDEX

HDEX ASSIST is a high-performance sportswear line derived from HDEX. Officially offered as a lineup for runners, it uses functional materials that provide features such as UV protection, cooling, moisture-wicking and quick-drying performance, stretch, and lightweight construction. Compared with regular HDEX apparel, it places greater emphasis on lightness and breathability while running, as well as functionality during exercise, and serves a role suited to running and high-intensity sports. While SUPPORT focuses on support for training in general, ASSIST is a line centered on running and movement performance.

HDEX SKIN is the first underwear line launched by HDEX, in 2025. Unlike regular training wear and sports bras, it focuses on items worn directly against the skin, such as bras and shorts made with seamless construction, four-way stretch, and three-dimensional designs. The line serves to extend HDEX’s sportswear offering into underwear and body base layers, positioning it differently from performance and outerwear lines for exercise, such as ASSIST and SUPPORT.

LIGHT SUPPORT is a functional line for women derived from HDEX’s 26SS EZ COLLECTION. The official archive clearly distinguishes it from the conventional SUPPORT line, which is intended for training and active multisports: LIGHT SUPPORT uses more flexible materials and gentler tension, making it suitable for light exercise such as Pilates and for everyday wear. It is a derivative line that retains SUPPORT’s supportive qualities while broadening the occasions and levels of exercise for which it is intended.

SUPPORT is a training-oriented line that continues to be developed under an independent name within “COLLECTION” on HDEX’s official website. Major retailers carry it as a “Support line” offering a fit suited to training and high-intensity multisport. It emphasizes a supportive fit and stability during exercise and is positioned not as an intermediary between HDEX’s general gymwear and LIGHT SUPPORT, which is lighter and intended for everyday exercise, but as a core line for high-intensity exercise.
