Chlorine exposure varies according to the amount of chemicals being used, the frequency of exposure, heat exposure, and the care taken to remove excess chlorine from your swimsuit each time it is worn. The terms "chlorine resistant" and "chlorine proof" refer to fabrics used for swimwear manufacture due to their ability to resist the fading and deterioration that chlorine exposure produces in fashion swimwear. Please be aware that some linings and soft cup bras used in swimwear may a spandex content that may not be resistant to chlorine exposure. Therefore, while your Chlorine resistant swimsuit fabric should hold up well over a reasonable time frame, the bra and linings could be the first areas to show fatigue and stretch. Due to all the above variables we do not offer or imply that our swimwear will last any specific amount of time. We do believe that our chlorine resistant swimsuits given to correct care will last longer than fashion swimsuits.
