There are several advantages to the wetsuit. It is rather light, not extremely expensive, requires little care, it is easy to get in and out and has few maintenance issues, aside from a rinse here and there. Once patch-up work is needed, a diver will usually go out and get another one from their local dive center or repair it with rubber glue.
So why are so many people moving to the dry suit? It is heavier, costs a heck of a lot more, and it is a pain at times to maintain and fix and sometimes, you can’t even get in a dry suit without the help of your buddy. Why go through all the extra hassles to dive in a dry suit? One word… comfort.
Though you can get a decent wetsuit for between $150.00 to $250, depending on the thickness, a good dry suit can easily cost you over a $2000+. Depending on how many dives you do a year and where you go, it may not be worth getting a dry suit – but consider this; with a dry suit, you are now able to dive in many more places that have spectacular diving and you can probably do so year round, rather than just 2 or 3 months out of the year.
The “Dry Suit vs Wet Suit” debate is one that has been going on forever. In the end, it is a matter of comfort more than anything else. Aside from what has already been mentioned, people who prefer the wetsuit may also pick a wetsuit out of comfort. They streamline better and almost feel like they are part of your body, without having to worry about its bulkiness and air in the suit and purging it.
Sure, this is only a matter of opinion and the type of warm water dives that so many divers do nowadays really only require a 3mm suit – and that is fine. But what about all those other dive sites were the water is below 80F?
The only winner out of a debate like this is the end user: you. What makes you comfortable and how much is that comfort worth to you? Where do you dive and how often?
