DESCRIPTION
Hyperlite Mountain Gear Southwest 55L - is a minimalist, ultralight pack designed for hikers tackling rugged, off-trail terrain where gear needs extra protection and durability is a must. Drawing on the proven designs of the Windrider and Junction, it delivers reliable performance with upgraded materials and fully solid external pockets for added toughness.
It’s built from Dyneema® Woven Composite 3.9, a 200-denier woven fabric that offers superior resistance to abrasion while remaining extremely lightweight and completely waterproof. Whether you’re navigating overgrown paths, scrambling across rocks, or bushwhacking through tight spaces, this pack is ready for the challenge.
Three external pockets made from Dyneema® Hardline fabric provide secure, snag-resistant storage for gear you want to keep shielded from rough conditions. The updated shapes and deeper side panels improve bottle access and keep essentials close at hand. Redesigned shoulder straps and a reinforced back panel boost carrying comfort, load control, and durability over time.
Inside, the pack offers 55 liters of internal space, closed with a roll-top system that lets you adjust volume on the fly. A simple hydration sleeve and oversized hip belt pockets make organization easy, while two removable aluminum stays and a supportive foam back panel help carry up to 18 kg with confidence.
Weighing in at just 874 grams (size M), the Southwest 55L is a dependable, purpose-built backpack for hikers who demand low weight without sacrificing strength or functionality in tough, remote environments.
