Osprey Pack Liner

While designed with Osprey packs in mind, the liner is compatible with any backpack that falls within the 30-50 liter capacity range. Its flexible polyester construction allows it to conform to the interior shape of most standard hiking packs.

The J-zip design allows you to open the liner wide, making it much easier to see and retrieve items buried at the bottom of your pack. Unlike roll-top liners that require you to dump out contents or dig blindly, this provides a clear view of your gear.

The liner is designed to provide a reliable barrier against rain and moisture, effectively keeping your gear dry during standard outdoor excursions. However, it is not intended for submersion or prolonged exposure to heavy, pressurized water.

At just over 4 ounces, the liner is extremely lightweight and adds negligible bulk to your setup. Most hikers find the trade-off for dry, organized gear well worth the minimal weight penalty.

Yes, it acts as a large internal compartment. While it is designed to line the entire main cavity of your pack, you can certainly use it to keep your sleeping bag and clothing dry and separated from wet items stored outside the liner.
