the predator is the lightest of the three, then hardwater, then climate. the climate is the first two blended together. if you take the liners out its equal to the predator, with them in its as warm as the hardwater. If your looking for a still warm but something you can layer under, get the guardian, or duckblind. Im on staff with them. Pm me if you have any other questions. I am running the predator this year which replaced the light, it has some new features like cross diagonal venting and pass through pockets on the bibs. Its a great suit I have had it out a few times and its plenty warm if your moving around and sitting for mid length periods of time. If I was planning on sitting on a pail all day I would wear my climate.
