That makes sense. There are some good things about them too of course. They are very comfortable to wear, can be adjusted to allow ventilation or not, they have many pockets for personal kit/food and they provide some protection against bumps etc.
The downside of your two piece is that rated survival times in the water are DRASTICALLY reduced.
