It's tough to find jeans that fit and look flattering on a tall skinny guy like me, but these do the trick.  Bonus points to Amazon for being one of the few retailers that carry them in my size (31x34... not even the Levi's store has them!).

These have a similar fit to classic 501s, but with a lower rise that is more fashionable and also much more flattering on a long-legged man.  I could use a little more room in the crotch and a bit of a boot cut would be nice, but overall the fit is very good.

The waist tabs are a cool detail but have no real practical purpose.  The snaps aren't very strong and will come unsnapped if you use the tabs to adjust the fit.  This isn't really a con for me though because the jeans fit me so well to begin with and I always wear a belt anyway.

The fabric is also great; it's soft and no break in period is necessary.

The color is a very nice dark blue, which allows them to be dressed up or dressed down.  I should mention that there was a lot of excess dye in these jeans.  I had to wash these several times before they stopped dying my legs blue (they also dyed the back of my messenger bag, which tends to rub against my thigh as I walk).  It's not an issue anymore now that I've had them for a couple months, but it was very frustrating in the beginning.

Update: I've had these jeans since August, 2010, and they are still going strong.  They have faded considerably and look super-casual with a lot of whiskering.  They are also prone to stretch a fair amount and need to be washed and dried on high heat after several wears to shrink them back down to a comfortable size.  Still, the denim has held up really well aside from some fraying on the left front pocket and they are still my go-to jeans.  Just wish I could find another pair in my size with this wash.
