I used to have a lot of BDU's, mostly Woodland or tiger stripe, some Blue, Some Black. I wore these to work everyday for several years. I was doing industrial maintenance and was crawling and climbing thru equipment all the time. They took the abuse, never had a blow out at all. The place where mine wore out at was on the thigh fronts. I think mainly from rubbing against equipment for so long. I'm down to about 3 decent pair and need to start stocking more of them. They are the most comfortable and useful pants I've ever work.
