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.
