Bought for 1.59 euros. I have tried the cover with a backpack that is approximately 45 cm high, 25 wide and 20 deep and covers it perfectly. I think that for somewhat older backpacks it also works because the one I have is loose. I have poured some water on it and in a minute it still does not happen, so I understand that it is waterproof. And message for people who make evaluations such as "I Love It", "It arrived well", "I have not opened it yet", "it is well in size" .. Or that they put photos of the product in their unopened bag, or of everything they have bought at the same time,... Stop wasting our time reading nonsense and if you write, put useful data that helps us decide whether to buy or not.

Decent quality. Waterproof. tested, see photos. More/less fits the miltec pack, but if you have any bigger accesorries, it will not fit most probably - see photos for back pack type.
Over all for that price, 100% RECOMMEND!

I ordered the 35l, it is very beautiful of good size and it looks very good material, it arrived quite quickly and it is the same as the photo that the seller has, you have to Take into account that when the backpack is placed there is a great possibility that it will come out from the top since it does not have anything to fasten it directly to the straps of the Backpack

Excellent cover for the backpack🙌, Waterproof (Umbrella material) and practical.

Excellent case and for its price is ideal to protect the backpack
