A 5mm or 7mm suit with a hooded vest and booties is all you needin the panhandlethe differance in 5mm and 7mm is the time it takes for the cold to work throught the suit. the 7mm will keep you warmer for a longer period. Another factor to consider is the depth. every 33 feet you go down the thickness of a wetsuit will decrease buy one half its thickness. So at 99 feet a 7 mm suit will be 1 3/4 mm thick. I dive year around and don't use or need gloves. I also use a 7mm farmer john suit and a hooded vest the hooded vest adds another 3mm to the upper torso. I also take a couple quart thermoses with hot water to pour down the suit before I enter the water on my second and next dives.
