Southwest 70



Hyperlite Mountain Gear channeled Edward Abbey when they designed the Southwest 70. Made for desert rats, this burly beast works perfectly for the longest, most inhospitable, arid trails or bushwhacking adventures. Though similar to Hyperlite's Windrider, they replaced mesh outer pockets that snag on brush with solid Dyneema® Hardline exterior pockets.

Use this big-volume expedition pack for multi-adventure travels to the most remote regions of the world where resupplies are infrequent. Other excellent uses for this pack include extended winter hikes or family trips where the kiddos aren’t yet carrying their own gear. Made from 100% waterproof Dyneema® Composite Fabrics (formerly Cuben Fiber) and with additional elastic frame sheet support for extra load carrying capacity, this ultralight backpack is highly durable and weatherproof. Organize and further protect your clothes, gear and sleeping bag from bad weather using Hyperlite Stuff Sacks.


Formerly known as the 4400 Southwest Pack. Packaging may have either name but the product is identical.

After a number of internal studies, Hyperlite has decided to remove the metal grommets from the weep holes of their packs. This product may ship with or without the grommet as they are phased out from Hyperlite's inventory.
The grommets were not an essential feature to the weep holes of the pack. Hyperlite has determined there is no physical function of these grommets and they have been merely for aesthetic purposes. Their design and production team has developed a consistent method of precision drilling the holes in the fabric. The heat generated from the friction from this process will seal the edges of the weep holes and eliminate the chance of the fabric fraying. This will now make the holes just as strong as when constructed with grommets.
