Just a question out of curiosity here. I am still happy and warm diving in my very old Bare 7mm neoprene drysuit. It is comfortable, very warm and dry. I have had to put a spot of glue on one tiny leak after stretching and mashing SiTech rings on the the arms, and the soles of my boots are wearing away, leaving me repairing disappearing rubber. And yes, it is a chore donning and doffing the thing. ... BUT:
I have noticed after a couple years diving with a very technical club, that all my technical dive buddies complain of this leak and that leak and this failed seem and that hole in their extremely expensive top-of-the-line trilam suits (some even have 2 suits so they can continue diving when sending one away for repairs). My friend recently emptied a completely flooded pro drysuit - he was also electrucuted by his expensive undergarment - ha ha). On the very same dive, his buddy also experienced a failure of his electrical cable - a common topic of conversation amongst these tech-crazy divers. They all dive with electric undersuits because they get cold, and even with those, they often shiver on the boat after the dive. They ask whether I'm cold and I smile and shake my head - I'm a thin guy and can get cold easily ... when not in my drysuit. I stay toasty warm in 8C water on an hour long dive (though with deco and safety stops doing nothing but hanging on a line, it can get a bit cool).
My very first suit was a thin trilam light suit and it ALWAYS leaked. After a couple years I gave up on it and bought the current Bare neoprene suit and was shocked at the difference. For the first time I was really, really warm and dry! At nearly 200 dives on this suit, I still am.
So this leads me to ask why neoprene disappeared years ago? Does fashion rule in such a technical industry? Why the trend away from Neoprene? Why do trilam suits seem to be such a constant source of wet spots and cold dives when they're considered the de facto standard in tech diving? What will I turn to when my old neoprene suite finally dies?
Very curious of peoples' opinions.
