I'm one of those people who lose body heat very quickly and need a lot of exposure protection so I've been mocked since I started diving back in 2000 because I wear a 5mm full suit over a diveskin and a 3mm snoopy cap to dive in 80+ degree water. he most common thing is being called a wimp.
My response is to smile and say, "Thank you!". When they go "Huh?" I tell them "Yes, I'm a wimp--I'm warm, inteligent, mature and perfect!"
I found that wearing gloves that have cuffs that are long enough to cover the veins on the inside of my wrists make a difference in how long it takes befre I feel too cold. If I am diving in a "No gloves" area, I use a set of neoprene wrist bands that I made from a non-repairable wet suit. I cut 2 rectangles that are three inches wide and as long as my wrist circumference, zigzag stitched the edges and sewed and glued the ends together.
