Osprey Backpack Liners

These liners are fully waterproof. They feature taped seams and a secure roll-top closure, which creates a reliable barrier against rain and moisture to keep your gear dry inside your pack.

Choose based on your pack's volume. The small size is designed for 30-50L packs, medium for 50-70L, and large for 70-100L. If you are between sizes, it is usually better to size up to ensure you have enough material to roll the top closure securely.

No, the liners are constructed from 40D ripstop nylon, which is specifically chosen for its ultralight properties. They provide essential weather protection without adding noticeable bulk or weight to your pack.

Yes. While designed by Osprey, the rectangular shape is optimized to fit seamlessly inside most standard hiking and backpacking packs, regardless of the brand.

Bluesign Approved materials indicate that the fabric was manufactured with a focus on sustainable and responsible production, minimizing environmental impact and ensuring chemical safety throughout the supply chain.

The 40D ripstop nylon is durable for general backpacking use, but it is not puncture-proof. You should still take care to pack sharp items like trekking poles or cooking stakes inside a protective case or wrap them to avoid damaging the liner.
