4/3 yes, wearing 4/3 with a poly shirt underneath, depending on the weather of the day, wind etc... perfectly comfortable.... a light detachable hood, alot of guys out there with no hood, some no gloves, i still wear 3mm gloves, 5 mm on the feet... stayed out for 2 and half hours no problem.... slowly peeling it away ...
Surfed Narragansett RI for the first time in a 4/3 on Monday night. It was fine. Actually had a few people next to me in 3/2's, and they were cold but still kicking. Water temp has got to be 50 something.
