  • 12/15/2017 Dolphin chlorine resistance always a winner

    5 Review Stars By Cts

    I have worn a dozen or more Dolphin chloroban suits in over 14 years at the fitness center. These last two are Dolphin Reliance so wasn’t sure what differences there might be. I am very happy with them and they seem to have a little more elasticity.  I have never had a problem and can wear each suit while others go through several different suits. I am 68, look younger but will not be submitting a photo. I workout in the pool for health reasons. My gym bag contains 5-6 Dolphin chlorine resistant suits at any time.

    5 Review Stars By Jaimee H.

    What can I say?  Dolfin makes a very good product.  I am especially pleased with their 100% polyester suits, which hold up almost for forever.  This suit is a bit lower in the leg than their Uglies, offering more coverage across the front and back, which is nice.  The poly stretches and fits snugly without binding.  The sides are cut quite low in this model but straps are comfortable and stay put with no slipping.  I got lots of compliments on the colors/pattern.  It will be great for teaching my water fitness classes!
