Chris, that 's great; virtually no duplication between this one and your others.Thanks Fanch, I just tried on one of my armored shirts and it will be comfortable, as the shirts fit so tight. The DD has larger upper arms and more of a pre-curve to the elbow, and the waist comes in tighter. I'll wear the DD more for just casual wear as opposed to this which will be for the bike. The DD leather is lighter and more flexible.
