Osprey Ultralight Pack Liner

This liner is designed for large-capacity packs with a 76L volume. While it can technically fit into smaller packs, the excess material may be bulky and difficult to manage inside a 50L bag.

The liner features waterproof fabric, sealed seams, and a secure roll-top closure to keep your gear dry in wet conditions. However, it is not intended for full submersion, so it should not be used as a dry bag for water sports.

The rectangular design is engineered to mimic the internal shape of most large hiking backpacks. This minimizes dead space and prevents the liner from bunching up, allowing you to pack your gear more efficiently.

The bluesign® certification ensures that the materials used in this liner were manufactured with a focus on environmental safety and resource efficiency. It confirms that the production process meets strict standards for chemical safety and sustainability.

The liner is made from 40D high-tenacity nylon, which balances a lightweight feel with the durability needed for typical backpacking. While it is tough, it is still a thin liner, so avoid dragging it directly against sharp rocks or abrasive surfaces.
