40–50L Waterproof Hiking Backpack Rain Cover

Protect an approximately 40–50L hiking or camping pack from rain and trail spray with a compact waterproof backpack rain cover. The lightweight nylon cover uses an elasticized edge for quick coverage and packs down easily inside your bag.

Waterproof rain coverage for 40–50L hiking backpacks

Fit depends on the loaded shape of the backpack, not only its stated capacity. External gear, tall pockets or an overfilled main compartment can change how the cover sits, so test it on your fully packed setup before a trip.

Fit and use guidance

• Load the backpack as it will be carried before checking the fit.

• Recheck the fit after attaching bottles, poles, pads or other external gear.

Wet-weather packing guidance

A rain cover protects the outside of the pack, but straps, openings and externally attached equipment can remain exposed depending on fit and conditions. Electronics, medications, documents and other moisture-sensitive items should still use appropriate internal protection.
