Chlorine resistant swimsuits are great. The Penbrooke swimsuits are 100% polyester and are specially made for hot tubs, high chlorine pools etc.The Penbrookes are guaranteed for a year from the date of purchase. Wash your swimsuits with a mild soap after every use to get all of the chlorine or other chemicals out of the fabric. Never machine wash or dry. Dry them indoors laying flat. The Roxanne and Gabar swimsuits are 92% polyester and will stand up in chlorine much better then Lycra, nylon, bathing suits but we do not recommend their use in hot tubs. The Gabar swimsuits go up to size 16. Our Roxanne bathing suits go from 34 to 42, 10 to 18 and in c, D, & DD bra sizes. Penbrooke crinkle swimwear comes in 8 to 18, women's plus sizes 18w to 26w, and some come in D cups.
