Yes, it means New Model. Just going by what the SKU tag says, this DE Totally has been remodeled in some ways. I can't believe we are 2 weeks away from release and we still don't know what is new with this piece (changes in straps or dimension... I know someone said that the pockets might be different somehow but they don't look it from the pics.. neither do the straps) or have good pics and info (ie: lining color/material).Sorry for the ignorance, but what does NM mean?
