I use the Endurance under the Poly Drag suit. It's my first Endurance suit but has lasted a year already and shows no signs of deterioration. The Poly suit lasts me 4-5 years and its always the stitching that goes but even then I don't worry about it much as I have the Endurance underneath and the drag suit is a drag suit. Ultimately, the elastic around the top crumbles and then its time for a new one. I tried the Endurance without the drag suit but found it traps air and then you have a bubble moving around when you swim. That was a bit unnerving.
