UnigearBackpack Rain Cover Waterproof Rating 5000mm, Ultraportable and Durable with 2 Anti-Slip Buckle Strap, Integrated Carry Pouch Design

Do know about long term usage but it fits my Northface Terra 55 back beautifully. Good buy

I bought one for me and one for my son just in case and boy did we need it! Day three on the AT and the sky opened up on us with a mile left on our trail. These covers were easy to put on and did a good job of keeping our gear dry. They are great purchase, especially for the price !

The cover just arrived. I ordered a Small based on the measurements of my favorite 16” IKEA family backpack, which is usually packed with lunch, wallet, book, small camera, etc. The rain cover was very easy to put on and hook. The fabric looks sturdy.I only wish it was wider - the cover stops just short of rounding the back. If I carried my water bottle in a side pocket, it would only cover part of the sides. I took off one star because of this. In this case perhaps using the circumference measurement of a filled backpack would have been a more useful guide when ordering.I like the fact that I can just unhook the vertical strap to reach the front pockets. No need to remove the whole cover. Since I carry most of my things in those pockets, I’ll likely use the cover even when it’s not raining. It’ll probably protect from soiling and give my backpack a longer life at a very low cost.

The rain cover (small) was a perfect fit for my Osprey daypack. It was easy to put on and easy to put back into its pouch after use.

I purchased this for my last multi-country trip and it held up well, surviving several trains', planes', and automobiles' baggage storages. It also protected my bag from getting dirty. My bag still looks very clean. I purchased a larger size so that I can tuck the straps and they don't get caught on conveyor belts during transport. My only caveat for this cover is that I wish it was just a little bit longer in length to fit my Osprey Aura AG 65L pack, which is more elongated.

I returned another cover that didn’t have the straps, but the straps are perfect for keeping it secure. I love the built in carrying case as well. The smallest size fits my Deuter 13L perfectly and matches the green color.

So far, I am very happy with the purchase ! It arrived today, the color (I ordered in the neon yellow/greenish) is exactly what it is advertised. It perfectly fits my Gregory backpack of 18L. If the back pack is full, there is not much space for anything else so if your backpack is closer to 20 L, or you are planning to add poles or extra water bottle, I would recommend to get a bigger size. The material seems to be durable and water resistant, however, I still need to try its performance under the rain !! I love the fact that it will stay in place as it has straps.

Fits my 58ltr pack perfectly, but tough to stuff back into its case. Probably designed to be stuffed by machine rather than a person. Not impossible just time consumingly difficult. Fine water resistance.

Perfect size for my new big wheeled back pack.Haven't tried it yet on rainy day.

Discreto y de buen material. Perfecto para transportar en la mochilita que forma parte del impermeable. Tiene unos broches ajustables en la parte de atrás que resultan muy eficientes a la hora de proteger la mochila. Las medidas son justo las que marcan las especificaciones.

It worked well while travelling and kept my day pack dry during rain. I really liked the clips and strap adjustments that kept the cover snug to protect all of my backpack. Fit perfectly for the size of my day pack.

The media could not be loaded.  La funda es de muy buen material y bonito color pero la pedí muy grande y no le quedó a mi mochila 🙄, la pedí en talla XL y le sobra mucho pero si me sirve para protegerla de la lluvia . Anexo video para que puedan ver el tamaño de mi mochila y el tamaño de la funda

I am happy with this purchase. I use it over a backpack I wear while riding my motorcycle and it works quite well but not perfectly. While the bulk of my backpack stays dry and I stay safe because drivers can see that reflective label, water still rolls down the back of my jacket and inside this shell. It then drips down the inside of the shell and accumulates at the bottom. The hole in the bottom of the shell is insufficient for evacuating this water so the bottom of my backpack gets wet along with everything in it that is located at the bottom. To address this, I put anything at the bottom of my backpack into a plastic bag.
