Hyperlite Mountain Gear's close-quarters pack

The Southwest 40 keeps you honest about packing smart and efficiently on weekends or section hikes, where the supplies you may need along the way are always within 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. Now made with a new, fully woven Dyneema® 200-denier fabric that offers more durability than ever with the same signature lightweight and 100% waterproof qualities that have made Dyneema a favorite fabric choice. This pack family is made specifically for tough adventures that would rip most other ultralight-style packs to shreds. 

Features:

  • Internal Frame: Integrated ¼” foam back panel pad, 2 removable aluminum stays 

  • Padded Hip Belt- featuring closed cell foam and spacer mesh, provides comfort and support for long hauls

  • Made with exclusive Dyneema® Woven Composite 3.9: this fabric provides exceptional abrasion resistance, feels better to touch, and reduces crinkling in cold conditions
  • Roll-top closure system with vertical compression straps allows you to adjust the pack's volume, keeping the load compact, stable and protected from weather
  • Top Y-strap provides compression and top-of-pack storage for gear
  • Two removable, contoured aluminum stays offer support and help distribute the load
  • Seams taped on all vertical side seams and behind sewn-on pack features enhance water resistance, keeping your gear protected from the weather
  • Sternum strap allows for easy adjustments along shoulder strap daisy chains
  • Redesigned shoulder straps feature an adjusted shape for a more natural curve around your neck 
  • More frequent bartacks provide increased sternum strap adjustment options, allowing for a customized fit
  • Removable side compression straps for versatile gear attachment options
  • Streamlined hydration system featuring a simple bladder hang loop and repositioned hydroport
  • Sewn-through back panel construction creates a curved shape that locks the interior panel in place, providing a more comfortable and durable fit
