I'm looking for suggestions on how to stay warmer when diving. I live and mostly dive in So Cal. I have a Waterproof brand 7mm full suit and a 5mm hood. The suit fits pretty well IMO but even though it's a tall, it still is not long enough in the arms for me, and I also lately seem to have more issues with cold water flushing down my back. I don't remember it being that bad when I started, so maybe the suit is getting stretched out a bit? Or I'm getting wimpier. I always get cold when diving but this past weekend I was miserable, and missed an opportunity to do a night dive because I was so cold.

We were diving in about 56F water, but we were doing Reef Check, which meant long dives (~50 mins to 1 hr) and we were barely moving around. I got cold to the point of it probably being dangerous, and I just could not warm up on the surface intervals. Others on the boat were cold, too, but I think I had it the worst. I was just shivering a lot and people kept asking if I was okay.

I had been thinking that I would eventually move to a drysuit, but I'm a new diver and learning to control buoyancy with a drysuit is intimidating. I haven't done it yet because of the cost, and that includes the fact that I'll have to take a class, and all the associated costs with that. Also this weekend some of the drysuit divers commented that with our shallow dives (30 feet and less), they couldn't add much air to their suits, so they were cold, too.

3 boat crew members have individually taken me aside without my asking and recommended that I consider a custom wetsuit that is a 2-piece farmer john and jacket. I'm really considering this, as it will be a lot less costly than the drysuit + class, and probably easier to use. There is a company nearby called JMJ that I am going to visit on Friday to see what they have. I'm leaning strongly toward this option, but my dive buddy is saying I should just get the drysuit.

Part of my concern is that I have GUE fundamentals coming up and I'm worried about that class. It's going to be difficult enough as it is, and if I'm freezing, it will be hard to think and learn. The class has been very expensive with all the extra gear I have had to buy, plus all the expenses of the class that seem to add up. I don't want to go into that class and not perform well or get the most out of it because I'm cold. I definitely can't get a drysuit before the class. One thing I'm going to try in the interim is wearing my 2.5mm full suit under my 7mm. If it will fit. :) If I order a custom wetsuit it can probably be ready by the time for my class.

I'm a real cold weather wimp. I always have on more layers than anyone else at work or pretty much anywhere. I dove with a 5mm suit in Cozumel this April and still managed to get a little chilly on dives. But this is not just a comfort issue at this point, it's a safety issue. It's hard to think and be on your toes when you are really cold.

Any advice would be appreciated.

Thanks!
 
I can relate. Your wetsuit has started to take a memory, the water here us getting cooler again, and you're likely moving less in the water with growing experience.

I'm pretty sure your gue instructor will encourage (coax, browbeat, cajole) you to go the drysuit route. This is manageable, but the learning curve is a bit longer. However, since it seems you're committed, I'd say this is really a good way to go. As you gain experience with bubble management, you can increase the amount of air in your suit so that you're comfortable shallow or deep.

A custom farmer john will also last longer (they use good neoprene at jmj) than your current suit and will be warmer.

With either choice, you'll likely need more weight. If you've got the resources, get both!

Based on your self-description in your post, I agree with your dive buddy. It IS expensive. You will not regret the investment (unless you get a cheap, leaky, or poorly fitting, suit).
 
Or you could get one of these battery-powered heated shirt/vest things to wear under your W suit. Cheaper than a dry suit. Probably cheaper than a custom wetsuit. I think I've seen them for under $500.

Also, you could try a hooded vest, instead of just a hood.

And/or something like Lavacore under your wetsuit. That adds roughly the equivalent of 2mm of neoprene in additional insulation and it is neutrally buoyant, so it doesn't change your weighting requirements.
 
A custom wetsuit will be around $500 according to the JMJ website. Maybe a little more.

What is a Lavacore? I have heard of them but it looks like they are not neoprene so I don't understand how they work.
 
Take a look at our 7mm suits. No zippers to leak, no neck seal to leak, super warm. If you fit within our k height and weight ranges , you will be very happy with the fit. We have men's and women's suits. These suits are made from Yamamoto rubber the best material available. You will be amazed how easy the suit is to put on when you use the proper lube....55 degrees.. You may be too warm at start of dive.

if you feel you want to go wet suit instead of dry suit, then get a custom fit. And a fitting!

I continue to see people layering on randomly shaped neoprene garments in their quest to stay warm. These are the same people that stare at me in my shorty (it's 7mm) as I get ready for the liveaboard night dive.

Wet suits only work if they fit. Stuff off the rack fits nobody.

We (my divebuddy & I) recently purchased new custom fit wetsuits from a mail order supplier (our local provider retired). My initial fit was just okay, her's was not. I used my new suit all week while she reverted to her old ratty worn out suit.

A fitting and final adjustment was part of our local providers service. We contacted our new supplier and they are also open to concept of "post purchase adjustments".

Warmth (happiness!) is a multi step process:
- get measured
- make the suit
- get a fitting
- make final suit adjustments
- dive happy...
 
Or you could get one of these battery-powered heated shirt/vest things to wear under your W suit. Cheaper than a dry suit. Probably cheaper than a custom wetsuit. I think I've seen them for under $500.
Yeah, basically the price you can find many drysuits.... While the thermalutions are still pretty unknown, so you won't find them second hand.

And/or something like Lavacore under your wetsuit. That adds roughly the equivalent of 2mm of neoprene in additional insulation and it is neutrally buoyant, so it doesn't change your weighting requirements.
Had one, made me actually at least as cold... And yes it was a proper fit.


I'd go for the drysuit... I've used one quite a bit in shallows (about 50 dives never deeper than 30ft), with a lot of air in it to compensate for my poor choice of undergarment... And never popped up to the surface as you seem be scared of.
 
I'm assuming you are taking fundamentals with Steven Millington or Hollywood Divers? I'd strongly suggest you don't show up with new drysuit you haven't gotten familiar with. The class is complex enough without adding that in, you won't get the best experience doing that. But they have a lot of experience in diving in SCal waters, contact them and ask them for suggestions. Having you freezing in class makes it really hard for everyone in class, including you and the instructor.

I took the GUE dry suit course from Stven Millington with about 50 dives in the suit and it was very useful.
 
A custom wetsuit will be around $500 according to the JMJ website. Maybe a little more.

What is a Lavacore? I have heard of them but it looks like they are not neoprene so I don't understand how they work.

Lavacore is basically a windproof/waterproof/breathable shell with a thin fleece lining. Most people seem to agree that it keeps them warmer. I.e. 5mm wetsuit + Lavacore is about the same as 7mm wetsuit. There is another brand call Sharkskin that is, I believe, basically the same thing.

I have several pieces of Lavacore and it works as advertised for me. I also use it under my dry suit, when it's cold enough to warrant using a dry suit.

Off the rack wetsuits don't fit everyone, but they do fit some people. ScubaPro EverFlex suits fit me perfectly. I wear my 3/2mm and have dived very comfortably in water that was 71F - on a number of occasions.

I have dived very comfortably in 52F water in a 7mm rental suit, with a Lavacore sleeveless full suit on underneath plus 5mm boots, Lavacore socks, and a 5 or 7mm (I can't remember) hood. No gloves.

Everybody is different and I have more bio-insulation than I should. So I'm not saying anyone else should be comfortable at the same temps with the same setup. I'm just saying that Lavacore works as advertised for me, and off-the-rack wetsuits CAN fit well (at least for some people) and seal well. And if it fits well and seals well, it will be as warm as it can be, for its thickness.
