I don’t know about you, but I love backpacks. When I first got married my wife wondered why I needed so many packs. I guess that was a legit question to ask. I can’t remember how I answered that questions but I am sure I said something like, “you know I need a different pack for snowboarding, and another for climbing and one for backpacking, etc.” This was true to a degree. But really I love backpacks. And I do love certain packs for certain activities. With that said if you are looking for one pack that can work for multiple activities, then the Mountainsmith Mayhem 35 is that pack.
