I wear 30/30 pants (32 for some jeans because everything is fucking skinny nowadays) and my snowboard pant size for a true fit is S. However, I always wear an M to have a little more room to layer and also because I don't want a fitted feel and look. M for a 686 pant for me (for example) is just medium baggy but not ridiculous. L is huge, jib kid Chris Bradshaw sized for sure. And M Nomis is pretty damned big, somewhere between an M and L 686.
It will depend on the brand. For you a 686 M would be right for you but if it's their "tailored" fit ( which I haven't tried) it won't be as baggy.
