G-Force Safety Underwear, Shirt, Long Sleeve, White, XX-Large, SFI 3.3/1

Would you jump from a plane without a reserve parachute? Of course not! This is the driver's backup plan. G-FORCE flame retardant underwear shirts provide a last line of defense as an additional barrier against fire and the resulting heat. The extra layer of flame-retardant material is an item that no driver should ever have to use, but if you should need it, you'll be glad you did! The soft-knit material is hypoallergenic and more comfortable on the skin than the old standby, and the double stitching provides added durability.
