All Jolyn swimwear styles are chlorine resistant! Jolyn’s swimwear is made with 100% polyester fabric. The greatest news is that even Jolyn’s lining is 100% polyester meaning that a customer’s suit will tackle the chlorine better than any other brand. Customers should always remember to thoroughly rinse the chlorine out of their suit after being in the pool, especially if they’re storing their suit away for any period of time.
