I have the Arctic Armor Plus. No frozen lakes in the south but it's still a warm suit. Great wind breaker while running to fishing hole at 50 mph. I have also tried it out and it will float you. I'm 265 lbs and it will keep you above water. Now I tried it in the summer just so I would know just in case I fall in. You cannot swim in it but just lay on your back and paddle. I paddled 100 yds or so across the river and back. Rested when I need to and made it just fine.
The sweetest of all sounds is (Get the nets that's a 3 lb'er)
