- Duramax is polyester/PBT
- BlackLine is Polyester/Polyamide/Spandex
When it comes to fit, Duramax stretches less than BlackLine, so a Duramax swimsuit will not fit as many body types as a BlackLine swimsuit.
When it comes to chlorine resistance, Duramax is more resistant, therefore a BlackLine swimsuit will not last as long in the water as a Duramax swimsuit.
The greatest advantage of the BlackLine fabric is that a BlackLine swimsuit unlined will not be transparent, while a Duramax unlined swimsuits run a high risk of being transparent..
Duramax is a manufacture with recycle material.
