FINAL SALE — Factory Seconds
On rugged and tight trails, the Southwest 55 is a flexible performer that can adapt and handle the way gear volumes change for weekend, section, or thru hikes. Ideal when resupply points are less frequent and/or for equipment flexibility is needed. When the extra volume is not in use, the 55’s top can roll down enough to make the overall size of the pack similar to the 40, but that additional space can come in pretty handy when you need it.
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.
