Levi's used to make a "Commuter" jean for bike riders. Gray, stretchy denim, water repellent, reflective stripe on the inside (showed when you rolled the cuff), gusset crotch (way more comfortable than the standard jeans crotch), high waistband in back, zippered stash pocket in the rear waistband (holds wallet, phone, etc, at a place where you're not bending). Since discontinued. I have two pairs and I treasure them.

Today, they make "commuter" versions of their regular jeans (541, 511) that have stretchy denim and reflective details. Spendy, though.
