I have not come across anthing on this subject personally, but my friend told me his brother heard about it and he's been looking into I guess. He was telling me that information has been floating around about the temperature is actually takes to reactivate a carbon lined suit.He heard that it takes temperatures way higher than what the average household dryer can produce to even reactivate the garment. Basically saying that the suits quit working? I don't know iftheir sourcesare reliable, but they are both reliable people and good hunters. Like I said it could be a rumor,but I thought I would bring it up and see if anyone else had heard this or would agree/disagree.
