Highly recommend these shorts by Fox:



The shell is pretty much indestructible; none of this thin flaccid crap you find most baggy mtb-style shorts. The area just below the waistline is lined with flex fabric. The seat is double-lined and reinforced.

No chamois (which I prefer around the city). Low-profile compression straps for a fit perfectly tailored by... you! They're on sale now for $38 bux. Can't beat 'em for longevity, comfort and fit. They don't look half bad either.
