Osprey Ultralight Protective Backpack Liner – Black, Medium

Osprey Ultralight Protective Backpack Liner

The medium Osprey Ultralight Protective Backpack Liner is shaped to integrate with your pack, creating a dedicated weather barrier between your gear and the elements. Its ultralight construction delivers weather protection without adding noticeable bulk, so your bag stays nimble as you move from trailhead to shelter.

The shape is tuned to work with your pack’s interior, so the liner sits securely in place instead of shifting with every step.
