Practically speaking, by covering the tuchus (*) in neoprene foam (usually black). I used to own a wetsuit made to my size (**). It kept me warm in 50 degree water.How does one snorkel and scuba dive in canada without freezing their tokhes off?
Certainly not a fellow diver, though. They will understand. I bet the cold water is way cleaner than the ocean around New York, too. I could barely see two meters in front of my nose.I am huge... so the thought of me in a wetsuit makes most people vomit
