Southwest 55

$379.00 - $399.00


Streamlined and optimized to help you avoid snagging your pack on the sharp, prickly vegetation that fills America’s deserts, the Southwest 55 replaces the Windrider’s mesh outer pockets with solid Dyneema® Hardline exterior pockets, but is otherwise the same award-winning pack.

Utilize this minimalist pack for bushwhacking adventures, winter excursions or for ultralight thru-hikes on the Pacific Crest Trail or the Continental Divide Trail where resupply opportunities are less frequent. Made from 100% waterproof Dyneema® Composite Fabrics (formerly Cuben Fiber), the Southwest 55 is highly durable and weatherproof. Organize and further protect your clothes, gear and sleeping bag from bad weather using Hyperlite's Stuff Sacks.


Formerly known as the 3400 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.
