AIRLUT Blue Color Nylon Backpack Rain Cover for Hiking Camping Traveling (Size: S)

These covers did a good job (no great) during a torrential downpour hike. I bought these to go over our girls' REI packs and sure enough we needed them on a long hike in NC this summer. We got caught in a pop-up thunderstorm and it poured on us for hours. The cover kept rain off the top, but it allowed water to pool in the bottom - the water that made it under the top because of the shoulder straps (these packs do not go up over the straps). Some covers have a small drain hole in the bottom, but this one does not . The water pooled there and allowed the bottom of the bag to get wet as a result. Overall, it kept most things dry, but a little drain hole would have made it perfect. All in all, I can recommend his cover - it is easy to use and waterproof. A solid four-star product.

Size was right for my backpack. Only used it once but it did work in the pouring rain while riding a bike (nice vacation!). Wish it rolled up a bit smaller but because it's a bit thicker material and more durable you get what you get. I keep it in the bottom of the backpack at all time. Wish it secured around the back a bit better. Depending on the layout of your straps it may slip off once in awhile. Also wish it had some access on the outside when you need to get in your backpack for something small.

Works as expected. We use them to cover school backpacks. The only additional feature that would be nice is if the top back portion was made to clip under the backpack straps because the cover does tend to ride up when you put the backpack on your back.

Needed a bag cover - got a bag cover. Its just what I wanted for a laptop bag cover.

This is a good back cover. It kept my pack dry in the Rainforest. It fits my 30L pack perfectly.

It looks like the cover fits and is just what my wife needs to keep her pack dry.

surprised at the good quality of the waterproof material
