The cotton thread makes sense since you probably want them to fall off. But that being said It would be kind of cool to have " Hoosier " permanently embedded in my chest.

 

Bob Rouleau added the fifth poll option. Thanks, Bob!

 

You beat me to it. Thats the difference between being on the east coast vs. left

 

Wait, now I get it; THREAD!

 

Switch to Carbon-X...it also wicks moisture and provides another layer of fire protection. Even a standard nomex T-shirt does a pretty good job of moving moisture away from your body. I'd rather not have low-temp melting fabric on underneath my suit. Would suck to survive the fire only to have a layer of plastic melted to my body while the medics try to treat my burns.

 

Is Carbon X light?

With that avatar?

 

Keep in mind that the level of protection we get from race suits is measured in very low number seconds. They do not work like fireman gear or stunt suits in the movies. By the time the patch catches fire and falls off from the thread burning through you are toast.

SFI Rating TPP Value Time to 2nd Degree Burn
3.2A/1... 3 Seconds
3.2A/3... 7 Seconds
3.2A/5... 10 Seconds
3.2A/10.. 19 Seconds
3.2A/15.. 30 Seconds
3.2A/20...40 Seconds

 

I wear it here in VA/NC under a three layer suit.

I am totally sold on the stuff after seeing a side by side test with Nomex. While the nomex chars and comes apart the carbon-x maintains it's shape.

 

Hence the reason I care more about the 'joints' where there is the least amount of protection. I'm very methodical about tucking the cuff of the pants into the boots and the cuff of the sleeves under the gloves.


I figure with my current 3 layer setup and carbonX undies I have about 10 seconds to 1st degree and 20 seconds to some second degrees and 30 seconds to a long stay in the burn unit.

 

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.

 

How about all the water in cool suit. Does it boil if on fire?

 

Wonderful.
Steam burn on top of the polyester patch wadding up into a hot plastic ball on the skin.


Those tubes of the coolsuit aren't low temp melt plastic, are they?

 

I sew on velcro and velcro the patches on for different clubs.

 

They melt pretty quickly but probably not in the time it will take you to exit the car. They certainly don't melt instantly when exposed to heat the way a poly moisture wicking shirt does. That said, you still want them on the OUTSIDE of your cotton shirt. Or preferably, buy one of the nomex or carbon-x cool shirts.
