The Docker's Signature D3 are my favorite type of pants.  Docker's D3 signature pants have the quality of Docker's with a bit more.  The D3 series brings with it an almost formal feature.  I feel comfortable wearing these pants everywhere.  I wouldn't feel out of place at a wedding, or a religious service, or other formal and nonformal functions.  I feel just as comfortable combining these D3 pants with a polo shirt on the golf course as I do with a sportcoat and tie at a formal event.
