I purchased the 803s first and I like me some slim pants so these came a little too loose but after washing them in hot water and machine drying them, they now fit perfectly. I'm a 30" waist and I fluctuate from 149 lbs to 155 lbs standing at 5'8.5".Unfortunately, the cut and fit for the same brand is wildly different. Per Michael Douglas Adam's stellar review of the 876s, I copped a pair but these are way too f-n' tight out the bag. Without even having washed them yet, they're already tighter than my shrunken 803s. The cut is actually really annoying because although the slim leg tubes are OK, whenever I bend over, the back of the pants shoot down and expose azz crack. Not a good cut imo.
