St.John

St.John features a 100% Polyester fabric that's extremely durable against the chlorine in the pool water (which is the substance that's responsible for the deterioration of the swimwear fabric).

Is it just a jammer? Yes, but with functionality in mind. Our St.John collection is a superb training jammer that has a 'anti-slip' tape attached to the leg opening. From our experience, having the sleeve slowly come up in the water as you are swimming can be really annoying. In order to address that issue, we applied a special aquatic anti-slip lining that's going to prevent that from happening, so you can concentrate on your laps without getting distracted. 

100% Polyester fabric + anti-slip functionality for the price of regular jammers from other brands. How can one say no to that?
