Zpacks Wide Mouth Dry Bag

The Zpacks Wide Mouth Dry Bag is a waterproof dry-bag liner with an adjustable size, so it can be rolled down tighter as its contents shrink rather than leaving dead air space. It's built to compress bulky items like a tent or a change of clothing down to their minimum packed size. Its 12-inch width is a deliberate choice: it's sized to fit horizontally inside a backpack rather than only running vertically, which matters if your pack's main compartment is wider than it is deep. It suits anyone packing a single main dry bag as a pack liner or for one specific bulky item, rather than someone needing multiple separate compartments for organisation.
