That was great advice. I'll keep mine short. I dive, surf, sail, etc.
Here in the gulf coast of TX., a tru dry suit is expensive overkill. I use my 'poor man's dry suit'. If it's really cold, various neoprene shortys or full suits, UNDER a 1 piece spray suit (water/wind proof). When it's not that cold, just the spraysuit. West Marine type, looks like a dry suit, but has velcro cuffs at the neck, wrists, and ankles.
With just the neoprene, get back on a boat from a capsize on a cold/windy day-now thats cold, like an evaporative cooler.
