If it's the same leather as the boots I had it's HH but not shell. The HH Viberg uses is thicker and mellower than shell. And I am pretty sure, though others will know more, that the horse "butt" they use is a higher quality leather than the horse "strip" used by White's and others. In any case this brown HH was a very rich color and a nicely thick leather. Again, I've seen very few boots in it, though there are a few pairs floating around..
