Pruvansay Waterproof Backpack Rain Cover, Portable Ultralight Durable Rainproof, Water Resistant Upgraded Version, Adjustable Buckle Strap Reflective Strip Storage Bag, Camping, Hiking (25-90L)

 This rain cover looks really good and the logo reflects very brightly at night, making it a good precautionary tactic. It folds into a smaller shape making it easier to carry and it's perfectly waterproof, as you can see from the video where I tested it

If you have ever been out with a backpack that is getting old and isn't really waterproof anymore, you know that a backpack can get really heavy. I picked the one to use with my day pack and picked the brightest color that i could to improve visibility on a dreary day. The cover comes in a protective zipper pocket that you can connect to the cover with the clip or just keep it protected in your pack when not in use. The only negatives that i have are that the buckles that hold the straps on the back are a bit bulky and might cause a bit of discomfort on your back. I do like that the buckles are there to keep the cover on as i have another that doesn't and it seems like it will slip off if the pack isn't full enough to keep the elastic tight.
