    I am thinking of switching to a dry hood for a serious cave project coming up. 4C water, 4 to 5 hour dives. Curious what users are wearing under theirs? Accelerate my learning curve please :D

    What type (or make) of dry hood are you planning to use? I have a latex drysuit with a dryhood and don't wear anything under the hood, even when diving cold 3-4 C water.

    Not sure how much hair you have, but don't see how 0.5mm of latex is warm at all without a hat or liner. Everyone I see here diving with dry hoods uses various types of hats. How long are your 4C dives?

    Not much hair, but my hood is different, made of thicker latex with thin textile lining. I have done 3+ hours in cold water, others much longer. It is made to measure and quite tight. Most people don't use anything under it.
    You can see the dryhood I am talking about in the first image:
    The cave divers who went back for their friends
    I am not connected to that operation. I posted the link only to show an image of the dryhood.

    I've gone through a few Viking Drysuits, and a DUI, with latex hoods and use the beanies that came with the suits. You need something to allow air to move within the hood and prevent an ear squeeze. There don't seem to be many folks who sell them, but a quick google for "drysuit hood liner" yielded this:

    Viking Open Cell Hood Liner | Dive Rescue International

    I'm guessing any Viking drysuit dealer can order one.

    That is a Loitokari dry hood, contact info Yritys historiaa | sukelluspukuoitokari.fi

    I have a neck/throat warmer fleece tube when using it.

    You could take a look at the 'K01' 5 or 8mm hood.
    It's not a dry hood, but it's extremely warm.
    If you have a good fit, parts of your head would still be dry.

    The Viking open cell hood liner is what I used with the Viking drysuit I had several years ago. Also installed a small one way valve on the top to allow air to escape.

    I have used 12mm hoods from Cricket at Otter Bay for many years.
    There's too much compression of neoprene hoods at depth among other reasons I want a dry hood. None of the divers in "Diving into the Unknown" are using wet hoods for instance. My project is a lot closer to those dives than not, so I am trying to up my exposure protection to arctic cave levels. Being almost as good is not good enough.

    I didn't know that included a liner :/
    I'm not sure how feasible it is to install one of those on my existing suit.
    Yea those are what I have seen locally - I was hoping to match what others are actually using in 3-4C caves for really extended dives.
