I couldn't test it in water because it's way too warm for the summer. I think the best time is autumn and winter. But I can still say something about the workmanship, the design, the fitting and the quality.
when unpacking it smelled pleasant and not chemical, just like a neoprene has to smell :) The entry success from above through what I think is normally large opening. That is so with this neoprene because you do not close it at the back but over a neoprene neck cuff which comes from behind then in front with an about 30 cm very robust zipper closes. This neoprene fits very well, I would have preferred to have taken a size bigger. But everyone should decide for themselves according to their personal feelings. The quality of all seams, applications and attached things looks very high. The design is very cool with the black, yellow, grey. I personally like it very much. Since the brand Mystic is not unknown to me, my decision to buy will probably fall on this fullsuit.
