The Hyperlite Mountain Gear Southwest 40L Ultralight Hiking Pack is crafted for rugged landscapes and demanding hikes. Made from 100% waterproof Dyneema® Composite fabric, this pack is as tough as it gets.

With three external Hardline pockets, you can access your gear easily without rummaging through the entire pack. The ultralight backpack with an internal frame provides remarkable support and comfort, while the roll-top closure and side compression straps keep everything secure and compact. You’ll also appreciate the hipbelt pockets for easy access to essentials on the go.
