Hike down dry river beds, bushwhack through scrub, and explore slot canyons with Hyperlite Mountain Gear's ultralight 2400 Southwest 40L Backpack storing everything you need for a minimalist overnighter. 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 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 seasons. 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 valuables, and top and side compression straps for a secure load.
