This fire resistant suit is being burned at 1,800 degrees Fahrenheit for about 12 seconds. If you were wearing this suit with that kind of fire attacking you, there's still a possibility you might suffer some second degree burns. But if you were wearing traditional fire retardent material, well, you'd be dead.
What's so special about this new suit? It's in the material. The material, designed by Lamination Technologies, uses artificial fibers spun into a fire-proof yarn. The material can withstand fire for a long time without ever burning. But the problem is our bodies can't do that. That's why the key of the suit is actually a brand new knitting process that traps air pockets to give even more protection from the fire. Hawt. [New Scientist via Pop Sci]
