Designed specifically to prevent snags in the rough scrub brush of America’s deserts, the Hyperlite Mountain Gear Southwest 40 differs from the Windrider 40 only in that it replaces the outer mesh pockets with three durable, ripstop Dyneema® Hardline pockets.

Use this highly functional and comfortable Hyperlite backpack for day trips, weekend hikes, section hiking or months on the trail where frequent resupply points are available, such as the Appalachian Trail, the Long Trail or the El Camino de Santiago. Made from 100% waterproof Dyneema® Composite Fabrics (formerly Cuben Fiber), the Southwest 40 is highly durable and weatherproof. Use this backpack with Hyperlite Stuff Sacks for a nearly perfect waterproof kit.


Formerly known as the 2400 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.
