Eco Swim Suits - A Use for Recycled Nylon

I recently needed a new lap swim suit and discovered the Speedo Women's PowerFLEX Eco,

which is made from 100% pre and post-consumer nylon yarn waste. According to the specs, the PowerFlex Eco retains its shape up to 10X longer than traditional swimwear fabrics. Seems like a win/win situation. This suit is available on Amazon. I can't think of any reason to buy a lap swim suit not made with recycled materials, can you?

My new swimsuit is made with 100% recycled nylon.
