Osprey Ultralight Raincover for Backpack

I was about to buy the Large (50 to 70L), and I’m so glad I read the reviews first. The Medium is more than big enough. It fits my Osprey Eja 48 perfectly, even when the pack is fully loaded, and still leaves enough room for gear attached to the outside.

I bought the Medium and it is a great fit for most 45-55L packs. At the upper end 50+ liters it is maxed out and will probably not work if you have things strapped to the outside of the pack but should accommodate bottles in side pockets. Osprey is zero help in giving actual dimensions but if it helps anyone, the Medium is sized as follows, measuring between the stitched seams: 29"h x 12.5"w x 11.5"d. Made from a light siliconized nylon fabric with taped seams that packs up super small and will remain waterproof for a long time. This material can be poked and abraded fairly easily so try to be careful with it in brush or when setting it down but it is reasonably durable. If you need higher durability, bite the bullet and get a heavier pack cover. A very nice feature of this pack cover that is not advertised or pictured often is that the bungee cinch cord can be looped over the hip belt (an opening on the cinch channel on each side). This keeps it from coming off in wind or when you need to get into the pack while not wearing it...simple idea to make it simpler to use. There is also a small light 3/8" clip buckle near the top, attached to the cinch cord that can provide additional security from it being blown or pushed off of the pack. Great product and I like it better than the similar Sea To Summit pack covers, and it's costs less, too.

I have an Osprey backpacking backpack and this rain cover was a perfect fit for it and very easy to put on and take off of the backpack. It’s lightweight and folds down nicely into the attached storage pouch. I’m very pleased with this product and would recommend it to others.

This product works great. It is waterproof, relatively lightweight, and compresses down into its own pouch. I got the large size which fit my 70L pack which also had a tarp strapped to the bottom. Wraps around your pack and has a clip that will be right at the top of your shoulder straps/pads which keeps the raincover snug and well attached. If you have an Osprey pack and need a raincover for it, get this one!

I purchased an Osprey Atmos 65AG size medium, and this cover is a very good fit. Even with the expansion pocket on the back containing rain gear consisting of a military issue rain poncho, as well as nicely pack-able goretex top and bottoms it had no problem covering everything. I did not have a ground pad strapped to it, as I have upgraded from a 20 year old original therma-rest to a Klymit model which packs up the size of a 1 quart water bottle (like a Nalgene) which I can now store in the side pocket of my pack. Depending on your choice of sleeping pad, it may or may not work with this cover, honestly I haven't taken the time to try putting my old pad on the outside and than putting on the Raincover. It is easy and quick to put on, just make sure the word "Osprey" is eight side up and you are all set. The only con I see is that with the pack I am using, the waist belt is partially exposed with the cover on, but I have given the whole pack a waterproofing treatment, so it shouldn't be a problem. I had heard other reviews where people mentioned that with the waist belt padding exposed, once wet they would wick moisture up into the covered portion of the pack. So, I spent $6 or so on a can of Atsko's Silicone Water-Guard at Walmart, they currently are selling 13.125 ounce cans which is an excellent price according to the research I have done on the product. Unlike other silicone based sprays that just fill the voids in the weave with silicone, rendering it waterproof yet unable to breathe, they have come up with a formula which waterproofs materials while leaving them breathable. I went so far as to use the product on some military issue ACU pants, and I can now form a pocket of the material, run it under the faucet, and the puddle stays on the outside for as long as I hold it, and once poured off, the inside remains dry, yet if you put it to your mouth, you CAN breath through the material. So I think I have solved the wet, wicking waist belt issue and while very light and compact, I find comfort in having the pack cover as well, as it feels sturdy enough to withstand scrapes from branches and such, barring I take a tumble in a cactus field. And it is definitely waterproof. I got in the shower with it, without the pack, and gave it an all over dousing looking for any possible weak spots, and I'm happy to report I didn't find any problems at all. I would recommend this cover to anyone with a pack that it would fit. As I say, mine is a 65 liter pack, and though it fit my pack pretty snugly, it I imagine it could work on a 70 liter, or possibly even slightly larger pack. It had some extra room to be sure, but not enough that I felt it was too large for my medium Atmos by any means. The only reason I did not give it 5 stars is because of the exposed waist belt, but that is really an issue with the pack more than the cover, it would be nice if they developed a cover that has some sort of sleeve to accomodate the waist padding/belt area, but until then, two thumbs up from me!

I bought this product for my Osprey Ariel 55. My pack is size small so it is technically only 52 liters. I initially bought the large rain cover because the description said a large started at 50 liters. When I got it, it as huge - obviously to accommodate larger packs. I liked that I would have a lot of room if I wanted to strap a lot of stuff to the outside. However, since I don't typically do that, I exchanged it for a medium. There is a huge size difference. The medium was definitely more snug and I liked the fit. I didn't want my cover getting caught and snagged on trees when I go backpacking so even though I probably cant strap much on my pack, it's great. I still had some room to attach on smaller items to the bottom and I would still be able to put rain gear in the front stretch pocket and water canteens on the side. If my pack was any larger or even a different shape, I might have had to keep the large. Also nice because there are strings that go around the hip belts so everything stays in place. The material definitely seems durable and I haven't tested in intense rain but hold up to humidity and light rain very well.

This item fits my Osprey Atmos 50 AG snugly. I was able to get the cover on with the pack fully loaded but it was a very tight fit. I haven't had this product for very long but it kept my gear dry during a heavy storm while backpacking a couple weeks ago. Definitely glad I had it! I haven't had any issues with durability but the material is thin so that's definitely something to be wary of.

S'adapte parfaitement à un Farpoint 40 Pliée la housse tiens dans la poche d'un pantalon

fits my osprey farpoint 75 trek perfectly and super small

Capa não se adapta bem na mochila. Na de 30 l fica muito folgada e na de 50 l muito justa

War ein Geschenk, hat sich sehr darüber gefreut. Der Regen Überzug passt sehr gut und super von der Qualität.

Hat selbst den härtesten Regen auf dem Skye Trail abgehalten. Im Rucksack hatte ich meine Sachen trotzdem noch in dry bags verpackt, aber das wäre nicht mal nötig gewesen. Super Produkt.
