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. Hyperlite Mountain Gear made this pack out of the same Dyneema rope fabric used to catch climbers when they fall, so you know it will last for many seasons to come. The Southwest also has a roll-top closure and taped seams for reliable protection in wet weather. There's an internal sleeve styled for hydration reservoirs (not included), and a loop designed for ice axes. The Southwest also has external snag-free pockets, zippered waist belt pockets for trail essentials, and top and side compression straps for a secure load.
