I have a McCall's pattern # 2815 that features loose-fitting pants in three lengths that have a fly front zipper, pocket and patch variations, and optional purchased drawstring. It is a men's sizes MM which is sizes 34-36-38.  This is a brand new, uncut pattern.  It is from a smoke-free home and shipping is free in the U.S.  Please check my other listings - I have many other patterns and will be glad to discount multiple purchases. I also have this pattern in other sizes.
