We invented SHEEX with one simple goal in mind: To help people sleep better so they can perform at their peak the next day. We strive to develop cutting-edge, high-quality sleep optimizing products that provide better sleep for athletes and all. Unlike soak-drenched cotton T-shirts and shorts, performance fabrics breathe better, wick moisture and stretch to move with your body. They keep athletes cool, dry and comfortable...Why wouldn't this same advanced material help produce an optimum sleep experience? After two years of research and development, we learned that these advanced materials do in fact create and maintain optimum conditions for deeper, more comfortable sleep. SHEEX Performance Sheets went to market in April 2009 as the world's first luxury bed sheets.
