Don't underestimate how much heat you can generate while swimming. You are using both arms and legs and that will put you into the same category as sports like cross-country skiing. In my competitive days, I could spend an entire day outside skiing and training wearing what most would find cool in an office - and that's at temps well below freezing. When I finish swimming (~2 km at a time in a pool) I am pumping out heat for quite a while afterwords - no towel can get me dry :-) That's another area where fitness is a benefit - you can generate heat for a longer time. Without training (either in the form of sports or hard work) your muscles don't store enough glycogen to keep going. That extends your time to survival. However, you do need insulation to prevent the generated heat from just transferring to the water as you move to keep warm.
