I wore these pants maybe twice during my wildland firefighting training. I got into Nursing school before I got a chance to use these properly. Some strings have come loose, but that happens with these (IYKYK). Take a good look at the pictures. Size M/R. Great condition!

Nomex® is an inherently flame-resistant fiber and has been a leader in heat and flame protection for more than 45 years. Because these lightweight and breathable wildland pants have FR fibers built into the fabric itself, they will maintain their size, shape, and dependability through repeated washings and wears.
