Designed specifically to prevent snags in the rough scrub brush of America鈥檚 deserts, the 2400 Southwest differs from the 2400 Windrider only in that it replaces the outer mesh pockets with three durable, ripstop Dyneema Hardline pockets. Use this highly functional and comfortable 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 2400 Southwest is highly durable and weatherproof. Use this backpack with Hyperlite Stuff Sacks for a nearly perfect waterproof kit.
