I took a punt on one of these and it just had its first trip on Saturday. The material feels closer to a Meander (which I got it to replace) than the Warmbac PVC suits. There is one pocket on the inside, none on the outside and the seams are sewn rather than welded. It also comes with a repair kit.
On the sizing front, according to the table on their website, at 6ft and 70kg I was just in the Large category. It's a tiny bit baggy on me, but the torso length is about right so I'm happy enough and will focus on eating more pies. The arms are about the right length for me, but the legs are about 6 inches too long though so will need a trim!
Can't really comment on how tough it is, but it survived a fairly gnarly first trip.
I'm happy with it so far. My only complaint is that when it arrived it stank of cigarette smoke!
