While making the Sleeve for the Wrist Brace, we focused on the ease of use and the efficiency of the product. Since the Brace is designed for prolonged use, we used moisture wicking fabrics that are also breathable. We continue to learn about materials-engineering so we can refine the design of our product and improve its performance. The sleeve’s design provides compression that is critical for blood circulation to the wrist during sport activities and injury prevention. This sleeve fully meets the set performance support for multi-sport participation and activation which has been extensively validated. The Wrist Brace Sleeves Shadowed Constitute Comfort and Performance. This sleeve is designed to provide comfort during active use.
