[QUOTE=Bryan Watts;6699439]When I was racing in series that required patches, I used cotton thread hand sewn though the outer layer (not shown in your list of options). I fail to see how some thin cotton thread burning away is a "safety" problem. If you are in the middle of a fire, the cotton thread holding your patches on is the absolute LEAST of your worries.

You have a good idea of the true protection. Most GOOD 3 layer suits are rated to the SFI 3.2A/5 or about 10 seconds to a second deg burn. Ten seconds can be a long or a very short time depending on the situation you are in. Suits are al just non burning insulation, more protection more heat resistance.
After a friend recently had a big fire in an Sports2000 I'm in the process of switching from single eye balaclavas to the double eye. He had very mild singes on his upper lip, nose and cheeks from the fire.
It is something I've always wondered about, along with the "Hats Off" helmet removal device now mandated in GrandAm, etc. We now have a large number of things that we can wear that aren't necessarily fire retardant but the suit we wear has to be. Double standard much?

An industrial manufacturer's perspective on flame resistant garments
In the making of industrial flame-retardant(FR) garments, patches are often applied. The basic recommendation is that patches be preferably made of FR material,threads and sew with FR thread. That's the best situation but also the most expensive. What you want to avoid is the patch burning on the suit and creating a hot spot. I guess, cotton thread is acceptable for patches as long as it doesn't affect the integrity of the suit.
As for undergarments, FR rated are the better choice. If not then avoid anything that would melt or burn. Imagine polyester melting on your skin.
Don't try and save money on your protective gear by not using it. FR garments will reduce burn injuries and even increase you survival rate vs burns. Remember that burn scarrying is permanent. Once scarred it's for life.
