The brand profile for 575 at kitmeout
says it's "... a
unique California jean for men and women alike." I think
they're now called 575/May 75. I own a few pair and
they're very nice. Great fit and nice looking to boot.
(I was searching here for info on them which is how I
happened upon this old thread.)
I own one pair of Genetic denim. VERY soft material and
nice relaxed fit. Would buy another pair of either anytime
(tho' I prefer the 575s). Both are TTS.
