Speaking of IH jeans, I think only model they are offering that comes as high as your bellybutton is 1955S. I have several their jeans, though most of them are variations of 634 and d Beatle busters, and they sit on the hip. BB's are nicer for riding a MC as their backrise is a bit higher...
So, as it's been said, measure your fav jeans and compare to their sizing and search between diff. models.
I don't know man, i have already compared measurements with all their range and nothing is even close to what i would feel comfortable with!
The beatle buster for example has an extra inch rear rise and an extra 1.8" at the front compared to what i wear...
That's a pretty sizable difference.
If i am going to pay the price of 4 pairs of jeans for a single one, they better be a fit i like!
