Mountain climbing requires gear to be a bit more demanding - it's just a symptom of the extremeness of the sport. So it makes sense that Epperson Mountaineering's USA-made Large Climb Pack - which is equipped with climbing-spec draw cords, zipper pulls, and a carabiner closure system - would be one of the toughest bags out there. And that makes it as great on a cliffside as it is for a daily commute. It also features a water-repellant 1000D Cordura exterior, 22.5 liters of internal space, four external zippered pockets, and mil-spec straps. If you want to incorporate a retro climbing aesthetic into your adventure or everyday gear, this pack is a superb option.
