Jeans are something that longer with a rinse and air dry than getting beaten to death in a washer and dryer. Of course, getting them dirty (real dirt) requires a wash. Otherwise, you can wear them for a while without a run through the machine.
My jeans (sadly, Levis, because they fit correctly) need a wash when dirt accumulates, usually about every 15 wearings.
My Pendleton wool shirts go several years between dry cleanings, probably 20 or so wearings (I have a collection of 14 of them, including my grandfather’s from the 1960s). Hung loosely for a day, they give up all scent and smell like nothing. I wear a long sleeved thermal t shirt underneath that soaks up all the deodorant and human smell.
I have a few wool coats that have never been washed, including my grandfather’s custom made Wyoming shearling from the 1970s.
I just bought a new pair of Levi’s. (Probably in 8 years or so.) Had to buy them online. Looking at the website they said something like “You don’t need to wash your jeans after every day wearing them. Wash them when they start to smell. Many people go 10 days between washes.”
I’m not so sure I go 10 days, but I will give them a sniff now and try to make them last longer.
A front loader is far easier on clothing of any sort. They just pick the clothes up and drop them so only their own wet weight impacts the water, rather than beating the fabric through the water.
