I have these

Good quality, the zipper works great, and they get the job done. My only real complaint is that over time (and neglect), the saltwater will deteriorate the taped seams, and that is where they will leak first. I never wore extra shoes or booties over the neoprene feet, so I'm sure the walks to and from the car to the launch spots also contributed to their early demise. If you take care of them, they will last you a very long time.
My next purchase will be a nice pair of Kokatat paddling pants from Andy at OEX.
