More leather on it than a Holstein! Great very storng " Flexable Frame " which was cutting edge in early 70's. Also first to use " Latereal Zippers on pockets for ease in reaching things in the bottom of your pockets without unload all the stuff to get to the bottom. First " Panel Loader Pack Ever " as well. This is the model I used on the thru-hike back in 1977 of the Pacific Crest Trail
