I have to say up front that we love Dockers, and they are a favorite of my husband.  He is a hard to find size, and Dockers are still the go-to pants for him.
We have tried other Dockers styles, but this style is perfect.  The D3 have a bit of extra elastic tucked in at the waist.
Dockers are very well made, and wear like iron.  And speaking of iron, I just have to catch these right out of the dryer and they hang without wrinkles.
So, my big guy is happy!!  Me, too!
