Zpacks Pack Liner

The Zpacks Pack Liner is a full-size roll-top dry bag shaped to line the entire inside of a backpack, protecting everything in the main compartment from rain in one go rather than relying on several individual stuff sacks. It is available in three sizes to match different pack volumes. This is the simpler, lighter approach to keeping gear dry in wet conditions, at the cost of the finer organisation that separate stuff sacks give you inside the pack.
