why don't people wear sweaters and sweat pants over their clothes? and a hat. so much heat is lost through the head! if i did have a snuggie the first thing i'd do is sew on a hood. when i go pond swimming in the fall and spring (in NewEngland), i didn't buy a wetsuit. i just wear the clothes i already have into the water. and sturdy hat. man, the hat makes all the difference.
