FINAL SALE — Factory Seconds
The Southwest 40 keeps you honest about packing smart and efficiently on weekend or section hikes where the supplies you may need to replace along the way are never too far out of reach.
When the route is thick with vegetation, requires the occasional up and over immovable objects, and calls for “suck in your gut and shimmy through” type moves, the Southwest is the backpack you want up-close and personal. This pack family is made specifically for tough adventures that would rip most other ultralight-style packs to shreds.
