The Kay collection was developed by our all-female design team with the goal of providing the best possible support, while being comfortable and transporting moisture away efficiently. Kay Blocked Tights - the moisture-wicking fabric will keep you cool and dry while the high waist keeps these tights in place. Kay High Waist Tights - the high-rise waistband of these tights keeps them up, even when you’re working out at a high intensity. Kay Sports Bra - The popularity is due, in part, to its versatility when it comes to different types of training. It provides the perfect support for high-intensity training but at the same time, it is soft and comfortable so that it also works excellently for more low-intensity exercises.
