From my experience and what I've heard, generally polyester swimsuits seem to last much longer than nylon ones. I had one 100% polyester which has lasted for some 10 months with almost daily swimming and is still in perfect shape. However nylon+spandex, though shorter lived, feels much more comfortable, more stretchy and easy to swim with (I think most competitive/racing suit are nylon blend, not polyester). So it seems each has its own advantage.
Also interested but not in poll questions: is your suit chlorine resistant or has sun/UV protection? Thanks :)
I buy EQ suits (http://www.eqswimwear.com/) in their lycra and rotate through 3 at a time through 4 practices a week. I never rinse them nor wash them and they last a minimum of 9 months. I have one that is over 2 years old and the lining just ripped but the suit is still in great shape and I'll still wear it. I buy the suits when they have their grab bag sale of buy 2 get one free so they come out to be about $17 each for women's. A great deal for great suits.
