I'm geting ready to order a Bare XCD2 Tech dry suit and am trying to figure out which type of neck seal to get. I'm a recreational diver and I do turn my head to look at things. Which one seals better? What are the advantages of each type?
Very much down to personal experience, but I prefer the comfort of a neoprene seal over latex. I don't find I get any leaks, no matter how much I look around, and I don't find them any more bother than latex. I have neoprene wrist seals too.
Sometimes the weather in the UK can be downright lousy for the entire day, and I can get into my suit first thing in the morning and stay in it till last thing at night and not have to worry. None of my buddies who wear suits with latex seals on the neck and wrists can stay in their suits that long without having some discomfort – the first thing they usually do on exiting the water and de-kitting is to get their head and arms out of the suits and leave the top hanging around their waist from the braces. Having said that, you will also find devotees of latex, so...
Drinking and diving do mix... I grab a beer as soon as the last dive of the day is over, as it is the best form of deco available – alcohol thins your blood, which means the nitrogen bubbles can get out easier! Believe me, DAN will be promoting this in a few years, I am just ahead of my time...
Used both, I prefer latex seals. have to be cut at the right size though. not too tight (strangling feeling) and not too loose (leaks). another advantage (for DUI drysuits at least) are ziplock style seals. These seals you can change yourself in less than a minute so it can save a dive.
I have a XCD2 Tech with neoprene neck and latex wrist seals. I have dove latex neck seals and greatly prefer neoprene. Mine has never leaked, is very warm and very comfortable. I suspect that neoprene got its reputation for leaking from earlier versions. The one that is available with the Bare suits is a great seal. Try it you will love it.
