My 13 year old son is also allergic to Neoprene. He suffers from eczema, too. Here are some things that I have learned:
You can contact DAN by clicking on "Send A Message" under "Contact DAN" on the left side panel of their home page. I don't think that Canada is considered a separate entity. While you're there, join. It's very reasaonable.
I received a reply to my message to DAN on this topic just today. Their dermatologists feel that the sensitivity is to one or more compounds used in the manufacture of the neoprene. As I had asked about Henderson's TriLAM suits, they mentioned that this might be a good alternative, and said that many who had tried alternative suit materials had good results, specifically mentioning vulcanized rubber, about which I know nothing.
Some alternative material suits are made with latex or neoprene cuffs and collars, so be wary of that.
My son has had this reaction 4 times. It pops up when he takes the suit off, so we shower him right on the dock and then dose him with Benadryl, to supress the reaction. Despite these efforts, it takes up to a month for the symptoms to recede. Not a nice thing.
I have spoken to Henderson, maker of the TriLAM suit, twice, but they cannot, or will not, provide a small sample of the material to allow us to do a test. I get the impression that they do not even want to speak with me - must be fear of liability.
Unfortunately, Henderson does not make booties in this, or any other non-neoprene material. Sheesh!
My son has been tested for synthetic rubber (that's what neoprene is) allergy, by patch test and scratch test, with negative results. That would tend to agree with the DAN dermatologists that the source of the problem is compounds used in making the material or the wet suits rather than the material, itself.
We tried lycra/fleece under suits (SharkSuits) but they were no help.
Is there anyone out there who has found a good alternative material? Anyone tried vulcanized rubber?
