The 20-40 L 4F Backpack Cover is a practical accessory for protecting your backpack in rain and changing weather conditions. If you're looking for a backpack cover with a water-repellent coating, elastic band, and reflective elements, this model is a functional choice for everyday use.

A DWR hydrophobic finish repels water, allowing drops to roll off the material's surface. The coating reduces moisture absorption and helps protect the backpack and its contents during rain.

The elastic band allows the cover to be adjusted to the shape of the backpack. This model fits backpacks with a capacity of 20–40 L , making it suitable for larger luggage sizes.

A Velcro bag makes storage and transport easy, and a hanging loop allows you to conveniently attach the cover when not in use. Reflective elements improve visibility after dark. Also check out 4F products and everyday wear options.
