Joy Walker Waterproof Backpack Rain Cover, 12000mm Ultra-Waterproof, Upgraded Ultra-Strong Multilayers, Antislip Buckle Strap

Tough and strong fabric! Holds up to a lot of mud and abuse. And amazing customer service if you do have any issues! I apparently dropped my pack with cover on onto something sharp, cutting a small hole in it - they sent me a brand new one for free and I had it within 2 days! Super easy to use, very lightweight, size was spot on for me.

We used the Medium rain covers in multiple days of rain while in Scotland, one of them on a hike in which the rain was hard-driven by tons of wind. Our backpacks always came out perfectly dry at the end of the day; and it is worth nothing that on the hard-driven rain day that even though my backpack stayed perfectly dry thanks to this excellent cover, my rain paints allowed moisture to seep through since the wind caused the rain to permeate my rain pants.One key part of keeping my pack dry IMHO is the clip and cinch straps that this rain cover uses. As opposed to a simply drawstring (that some competing packs offered and which I tried on at home in comparison), the clip cinch mechanism worked perfectly to keep a tight fit over the pack, offering more coverage over the portion of the pack that touches my back than did other covers which used drawstrings. Prior to using this pack I had incorrectly feared that the clip/straps on my back while hiking, but what I found was that as long as I oriented the rain cover such that one clip receptacle was at the top of the pack (as opposed to the bottom of the pack), that I happily never felt any of the clips or straps while hiking.Also, the rain cover was very easy to put on and to remove. I'd highly recommend this rain cover.----TLDR---A week prior to embarking on a 3+ week trip to Scotland&Ireland in October, I was told that I had better get a rain cover for my backpack/daypack because hiking there will involve frequent hard-driven rains.I bought three different rain covers and at home I did a fit-test over my fully loaded daypack (a 32 liter Osprey Skarab 32) and over my wife's somewhat loaded 28L Osprey Skimmer 28 as well (I say somewhat loaded because she never packs her pack as full as I pack mine, and her pack is also smaller, so we wanted to make sure that the medium wasn't too big for her pack....it wasn't; it fit both our packs perfectly). The Joy Walker MEDIUM offered the best fit and the best coverage due to it's dual click and cinch straps (as opposed to the drawstring method offered in some rain covers).FYI, the three covers that I purchased and tried on our packs at home were:REI Co-op Duck's Back Rain Cover XS (it fit the pack, but the drawstring cinching mechanism allowed more areas for wind-driven rain to get into the pack than did the Joy Walker's clip and cinch mechanism)Joy Walker small (too small for a fully loaded 32L pack)Joy Walker medium (perfect size for my 32L pack and for my wife's 28L Osprey Skimmer)

I got this laptop cover for my son's laptop backpack. It's a great product that looks durable and fits well. It provides good coverage and the straps keep it in place. I know it will protect well from rain!

For those who own the Osprey Volt (60L) and Osprey Viva (50L) packs, I found that the XXL size is almost perfectly suited for the Volt pack, and marginally too large for the Osprey Viva but acceptable for use.The criteria I used for this is assuming that you are using a fully loaded pack WITH an item (tent, sleeping pad or sleeping bag) attached to the outside bottom of the backpack using the carrying straps specifically for that purpose. I would find that the XXL size would fit somewhat snug over a Volt bag combination with a foam sleeping pad attached to the pack; the Viva obviously fits but with a bit more slack. There's not much consequence to the additional slack with the Viva but it does mean that the rain cover flaps in the breeze pretty annoyingly unless you take the additional time to cinch it down with bungees or the like.As far as the raincover itself, there's really not a lot to screw up here. It's a large piece of fairly thick nylon with an elastic to fit around your backpack, plus two straps for either vertical or horizontal fitment around the backpack. I typically only use the horizontal straps for easier access to the top openings of my pack, but if it's windy out I also attach the vertical straps to my pack. It also comes in a stuff sack, but I usually ditch it and keep the raincover as a sort of liner for the inside of my pack- this saves just a tiny bit of weight, plus the stuff sack is made of some weird mousefur/low pile microfiber material that's at odds with the rain-resistant smooth nylon raincover it's supposed to carry. One thing I did wish it had was a way to guarantee the top is secured over the top of my bag. I typically use a small chip or binder clip for this purpose but it would be nice if it had an eyelet so I can attach a nite-ize twist tie or carabiner to the grab handle of my pack.As far as actual usage of the raincover: The elastic is actually pretty nice- it does a very good job of holding the raincover to the backpack and stretches wide enough to easily swallow my pack even with a protruding sleeping pad attached to the bottom of my pack. I used this during a trip to Yushan in Taiwan- I would not call conditions torrential per se, but I did have to hike 6 hours in steady rain that wet out the DWR layer of my rain jacket. While I did find that the nylon itself just about wet out on the raincover, my pack stayed dry. For the price, the raincover did its job. I have to assume that you can buy lighter weight raincovers that are slightly more water resistant and fit better to specific packs, but for the price this is a very good general option.

This backpack cover is all you need. I’ve taken it on rucks and it’s worked perfectly, all my stuff inside was completely dry. The straps are adjustable so if you did get a size that was too large it will still cover it completely. The customer service is excellent, if you need anything even a new size they’ll send one to you. Overall just a great product with great service.

I ordered a cover size L for waterproofing two bags attached to my motorcycle . The cover was too small so I reach out to the supplier by e-mail , they responded very quickly with an offer for a bigger size cover and expedite it to me free of charge. The new size was perfect. The tissue material looks strong and the straps works well.Great customer service and product.
