Why We Like The 4400 Southwest 70L Backpack

Spend a week trekking around the desert with all the camping gear you need tucked into Hyperlight Mountain Gear's ultralight 4400 Southwest Backpack. Despite its ultralight weight, the Southwest is surprisingly comfortable and durable enough for long hikes. Its Dyneema Hardline suspension system includes spacer mesh foam at the shoulder straps, back panel, and waist belt, and there are supportive aluminum stays that you can remove for even less weight.


  • Ultralight backpack built for weekenders and weeklong thru-hikes
  • Dyneema Hardline suspension system is minimalist and fully adjustable
  • Removable aluminum stays ensure rigid support
  • Padded, spacer mesh shoulder straps and waist belt for comfort
  • Roll-top closure customizes capacity with a secure fit
  • Fully taped seams and waterproof fabric offer 4-season versatility
  • Hydration compatible sleeve and port sized for more reservoirs
  • Ice axe loop and side compression straps
  • External Dyneema pockets and zippered waist belt pockets
  • Item #HMG000A
