Hey jeanswest fans!

I bought a pair recently (bootleg) but I'm not entirely happy. I find that they go sacky around the crotch too quickly (ie a couple of hours of wear after the last watch). Also the black stretchy section is kind of odd, I feel it will last me to 9 months but at this stage it's kind of ... sacky too! And hot. Not too mention that i'm constantly yanking them up

Anybody else having these issues?
