Do yourself a favor and trek with Hyperlite Mountain Gear's ultralight 4400 Windrider Backpack, because a week's worth of camping gear is heavy enough. Despite its ultralight weight, the Windrider is surprisingly comfortable and durable to handle 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.
