i have a warmbac PVC as my digging suit, i'm now on the second one as they are great for our dig - leave suit to dry hung up, roll it out and all the clay/mud falls off - so easy clean. It has no shrinkage, so you don't need to allow for that at all like the cordura ones do a bit. Also the one thing i found good was that as it wore, it just wore through, despite abuse, it didn't tear, it just got thinner and thinner over time. Initially i was concerned about any wear-points, but the fact that they didn't wear through or tear was a real positive for me. My old suit, while the material is now very thin has no holes or tears still and although very porous, is still quite usable. I felt i got value for money on my abuse levels on it.
