I can't give you a comparison, however, I can say that the law has worked great for me. I feel it's one of the least "bulky" CGA vests that I've checked out. Very comfy.
Again, there will be plenty of options, so try and go with what works, and fits best, for you....or your husband.
I gotta say, I hate the name......cuz I'm always trying to keep "the law" OFF my back..
I know, that was weak......but how bout a courtesy laugh?
