Osprey Pack Liner

This liner is designed for large-capacity packs between 70 and 100 liters. Its rectangular shape is specifically engineered to slide into these larger frames without creating awkward bulk or wasted space.

It is fully waterproof. The combination of waterproof-coated fabric, sealed seams, and a secure roll-top closure creates a reliable barrier that keeps your gear dry even in heavy rain or wet trail conditions.

To seal the liner, you fold the top opening down on itself several times and secure it with the buckle. This creates a tight, water-resistant seal that prevents moisture from leaking into the main compartment.

While a rain cover protects the outside of your pack, a pack liner is the most effective way to guarantee your internal gear stays dry. Many experienced hikers use both for maximum protection, but the liner is your primary defense against water soaking through the pack fabric.

Absolutely. Because it is essentially a large, waterproof dry bag, it works well for any activity where you need to keep gear dry, such as kayaking, canoeing, or storing wet clothes after a trip.
