Tim, you make a good point about insulation under the suit. A couple years ago a sea kayaker off the New Jersey coast capsized just outside the break. It was winter. The water was cold. The paddler was wearing a drysuit, but he didn't have much for insulating layers underneath. He died within view of onlookers standing on the beach (who couldn't go out after him due to the cold water).



So, be sure to pay as much attention to what you wear under the suit as you do to the suit itself. Dress for the water temp, not the air temp. (If the water is cold, like where I sail, you will also find that the air temp can be up to 20 degrees cooler once offshore as it is cooled by the frigid water.)
