Osprey Raincover

Yes, the draw cord closure system is designed to be highly adjustable, allowing it to cinch securely around a wide variety of backpack shapes and sizes, regardless of the brand.

It is designed to pack into its own integrated pouch, making it roughly the size of a small, lightweight accessory. It takes up very little room in your pack's side or hip-belt pockets.

The cover uses high-tenacity nylon with taped seams to keep your gear dry during rain. While it is highly water-resistant, it is designed for external protection and should not be submerged in water.

DWR stands for Durable Water Repellent, which is the coating that makes water bead off the fabric. Osprey uses a formula that avoids PFAS chemicals, which are often used in traditional coatings but are known to be harmful to the environment.

It is made from 40D high-tenacity nylon, which balances lightweight packability with necessary durability. While it is tough enough for standard trail use, you should still be mindful of sharp branches or rocks that could snag the fabric.
