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. 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 multiple seasons. The Windrider also has a roll-top closure and taped seams for reliable protection in wet weather. There's an internal sleeve styled for hydration reservoirs, and a loop designed for ice axes. The Windrider also has external mesh pockets, zippered waist belt pockets for valuables, and top and side compression straps for a secure load.
