    I'm sure I will too as I progress. Being the first time I had used a hood, my understanding of a perfect fit was limited.

    You might find that your hood needs trimming. I have had to do that a couple of times to prevent the mask &hood interfering with each other.

    The downside of hoods is a loss of a bit of the freedom of movement but that is more than made up for by the retention of heat. There is a trade off between thickness/heat retention and movement - the thicker the hood, the more heat it retains but the harder it is to move. What level of trade off you are willing to accept is up to you.

    A few folks have mentioned trimming it. I'll do some research and more testing to see if that's going to be needed.

    Thanks

    After you adjusted and pulled the hood back, did it creep back down and break the seal of your mask again?

    For me, I find the hood will push back down again, hence the slight trimming solving that problem.

    But of course, experiment before cutting.

    Ayisha, it didn't actually. Once I figured out how to adjust everything, the dive went just fine, no additional flooding. Just the restriction of moving my head left/right/down.

    Marie13, I've been looking at waterproof dive hoods, heard nothing but good things so far, just wondering on the fit I'm sorta in between size in your option if I go with the larger size do you think it will still be snug enough around the face?

    If that helps there is a size guide on these page.

    also there is a warning that while the brand is Waterproof, the hood is not waterproof
    :p

    I have a K01 hood, which is extremely warm.
