Subsea Greeneck

I give it a 3 out of 5. The elements do get warm, but you have charge the battery every hour or so. I have a 3AmpHour battery that lasted about 2.5 hours. I didn't need an overcoat, but at warmer temperatures, it can get hot. Also, after using the hoodie 100 times, I washed it as recommended and the element wire shifted, mostly, to the button side. No heat on my right nor back. I had to cut the inside cloth to place the elements back; to do this, I had to sew them back in place. Poor design as far as durability.
