I have "blown out" more than one pair of nylon shorts and pants while hiking. I sometimes wonder if going back to jeans would be easier( definitely cheaper)!
In the old days (50s through 70s I wore jeans always a new pair washed several times. I blew out several pairs. Since then I have relied on synthetics and have not had that problem. Have had couple pairs resewn along seams when they seemed a little worn but the fabric seems much more resistant to wearing and tearing but maybe I'm just not as tough on my pants as I used to be now that I'm an old fart.
