I've done that at least two winters of Delaware / MD surfing when the water never got below 45 and the weather wasn't brutal cold when there were waves. The hood was attached to a hotskin vest. It was totally doable FOR THOSE WINTERS. NOT for others. Its mostly about quality equipment...the 3/2 has to be decent with sealed seams, tight openings and fit properly..and attitude...and making the drops.
NO BS. usually i don't wear a hood until real late, i don't know if it is because i am part canadian or diabetic, but i deal with the cold well
if you really need that thick of a wet suit you are probably a starved ethiopian. its still trunkable out. and at worst all you need a is a spring suit.
KB4L trunked it yesterday, of course he is 5'7" 260 with skin thicker than a fur seal. His epidermis alone is 7 mil. I mean are you wearing long johns under ski bibs when the air is in the upper 60's? In that case a 5 mil should suffice, but may I suggest 5 mil boots, lobster gloves and boots? Also, drive to the beach suited up while drinking hot coffee and leave your mom's minivan running with the heat on.
I wore a 4/3 one early morning session last week with offshores and was comfortable. Wore it monday mid-day and had to leave the back unzipped to let cooler water in becasue it was blazing hot. If the air temp is like it is today i will be back in the shorts and 2 mil top. And I definitely have used my 4/3, 5 mil gloves, 3 mil boots, and hood from dec-april the past 2 years with no problems. I probably only get out 10 times or so in the winter though. Our winters have been pretty mild in delmarva the past few years, lets hope for another.
4/3 for three winters straight i wore a oniel 4.3 w/3 mil xcel gloves and 5 xcel mil boots. no jokes. and i surf alot. my sessions last longer then anyones, except jordy. of course if i am not surfing i m paddling alot also-i never stop. buuuuuut...the last three winters have been very warm for the midatlantic. anyways, trunked it yesterday again. this weekend will be a short sleeve full, but hoping for a shorty.
