Wranglers at Walmart----they seem to have most sizes covered---regular and relaxed fit---straight blue and various shades of fading---fairly heavy duty.
$100 bucks gets you 6 pairs with change left over.
Levi's rarely last more than a few months ---with the crotch always ripping out first----when the price went out to $40 a pair, I stopped buying Levi's altogether---that was over 15 years ago and they lost me forever.
You know I haven't tried Wranglers, and I'm not sure if the cut would work for me or not, but I have looked them up and down in the store, and they seem to be really good basic inexpensive durable work pants. In spite of the fact that I've grown enamored of high quality selvedge denim, I gotta say, that's really what jeans SHOULD be. I love my Gustins, they are just about my perfect jean, but I wouldn't turn up my nose at a pair of Wranglers for $25 if they fit well and looked good on me. the 13MWZ looks a bit high waisted for my preference, but the 47MWZ in rigid might make a nice value jean. I might just try a pair on next time I'm at Tractor Supply.
