Lifespan of shorts?

[Becky]

"Not staying put" absent some obvious sign of wear is probably more a change in your body than it is in your shorts.

Interesting...I've never worn a pair of shorts to the point of transparency, but I've chucked plenty due to a loss of compression and thus increased movement of the chamois. I haven't really lost any weight, I try them on prior to buying, and the size charts say I'm in the right size, but maybe I need to try a size smaller....

I'm still curious how long others' shorts last them. I'm a data geek that way.
