Sweatpants for the hubby

My husband has been asking me for quite some time now to make him a pair of sweatpants.  He wanted the sweatpants to have a zipper fly on them but a whole waistband with elastic and a drawstring.  I figured that I could use the Simplicity 2318 pattern and alter it for a fly zipper.

I think that the fit could be improved but my husband is happy with them and says that they fit just the way he wants them to. He has asked me to make him more.
