Questions and Answers for ONeill 5mm Sector FSW Firewall Mens Wetsuit:

  • Kyle:

    What would be good for going wakeboarding in? in like 60 degrees of water?

    Bill  (Certified Scuba Instructor at

    Good suit for that. The waist and chest are the most important measurements for the fit with a wetsuit. Height usually will work even if it is one to two inches short or tall. Weight will depend on the divers body build and is the last measurement to consider.

    i just bought a used bare junior size 12 full wetsuit but the tag doesnt say anything about it water temp, type, mm, etc. i purchased it to resell but would like to know what im also considering keeping it and giving it to my nephew as a gift...we live on the eastern shore of va.....the suit is all black with white stitching and a dark grey chest area. there is a vertical zipper up the back and a large trademark bare going down the side panel of the right leg. if this isnt good for the water temps up here this time of year, what would be and why wouldnt this one work? i looked at discontinued suits but didnt see this one...can anyone tell me what i bought please?

    The best thing to do is email picture to the manufacturer to identify the suit.

  • Leonardo:

    Hello. Seemingly I have to get a small or a medium size according to my body measurements. (177cm tall, chest 96cm, and waist 82 or 83cmm) I have I to buy, the tighter or the loose one? Thank you.

    Darrick  (Certified Scuba Instructor at

    Hello Leonardo, when you are sizing a wet suit the two most important measurements are your chest/bust and waist. Height is a secondary measurements and your weight is the last measurement. You do want your suit to fit snug not uncomfortable.
