IEDs. RPGs. The heat. The cold. They're all constant threats. That's why soldiers need every advantage they can get to protect themselves. CORDURA Baselayer fabric is one of those advantages. A high-performance knit engineered from a proprietary blend of INVISTA T420 nylon and cotton, CORDURA Baselayer fabric is 6x more abrasion resistant than 100% cotton. It's comfortable and versatile in all climates with FlatLock seam construction throughout to reduce friction. Absorbs moisture quickly and won't melt or drip like polyester. Helps protect against flash fires and reduces burn injuries severity by charring as opposed to melting.
