Check out the original MSR pack I have on my back. It was one I bought from
Larry Penberthy out of his garage before the name MSR meant anything. He had just created his
Thunderbird Ice axe and was creating packs that he thought he'd could improve the design on. I used this pack for twenty five years and today my son in law has it. I still have my Thunderbird Ice axe, it is a treasure although I use a Raven Pro when I go out today.
