It seems their pants—which are completely new and supposed to be more durable than previous models—can't survive the rigors of the desert. They're ripping apart seemingly at random. The new pants seemed perfectly fine. They use tightly stitched flame-resistant Defender M fabrics and Christian at Kit Up! says their "crotch design" is fine! But they can't survive up to the daily life of Army soldiers, and they get ripped right, left and center. The problem is so bad that the Army had to get back to select a new fabric, 40% stronger than the current material.
