Questions and Answers for ONeill 7mm J-TYPE FSW Fullsuit with Hood:

  • Joshua:

    How much weight would I need If I was to wear the ONeill 7mm J-TYPE FSW Fullsuit with Hood stand-alone without a SCUBA unit? By the way, I am 120 pounds, if that helps at all.

    Darrick  (Certified Scuba Instructor at

    Hello Joshua, I would suggest going with 12 lbs to start and adjust from there take off weight or add weight.

  • Joshua:

    Will a full face mask create a water-tight seal if I place it on the hood instead of my skin? Or is the hood not the right material for a full face mask?

    Darrick  (Certified Scuba Instructor at

    Hello Joshua, to get the best fit I would suggest sealing this to your face not the hood. You will have less chance for your mask to leak with contact to the face and not the hood.

  • Shawn:

    Is there a significant amount of water that flushes through the hood since it is velcroed on in only one spot?

    Bob  (Certified Scuba Instructor at

    No. At least not any more or less than any other hood for scuba.
