I believe 010 has regular drawstrings and 011 are the 3M. The grey I have with non 3M drawstrings seem to fit a little larger, too. One of the TF experts will have to confirm though.
I have -011 and they have regular drawstring on the waist. But that little drawstring on zippered pocket do have 3m.not sure which is which. the draw string with 3m are the newer releases that have more of a tapered/fitted fit where as the pair with no 3m in the drawstring has more of a looser fit. i prefer the old pair's cut honestly. and the material on the newer pair feels kinda "thin"
