Review on FANCYWING Waterproof Backpack Rain Cover | Reflective Strap | Upgraded 10-90L Non-Slip Rainproof Cover for Hiking, Camping, Hunting, Cycling in Rain, and More by David Flores

I ordered three backpack cases to look at. This was the largest of the three and while well made I ended up sticking with the one that fit better and was more compactly packaged. I like the drain hole feature. But if you don't get the right size, the hole will be too high when water hits the bottom during high tide. I ordered this size XL. What I left behind was the ZM-SPORTS in size XL. They are different sizes that I see now. 50-65L (ZM Sports) vs. 65-90L (Fancywing) Because I have stuff in the pockets of the pack and strapped to the outside, I did not order the size recommended for a 40L pack.
