Question: What size should I get for the Kestrel 48 M/L?
Document: I mostly use the pack on a bike or while running so I down-sized the cover to prevent excess material. I bought the X-Small for my M/L Talon 22 and it fits perfect, no flapping!Have only used in a light rain, but so far waterproof.
I bought the Osprey Atmos 65 Pack and the size Medium rain cover fits it perfectly. The cover comes in a little mesh bag but the cover folds up into itself into a bag thats attached to the cover. This isn't something I hope to ever really need but it is good to have just incase. I was able to get mine for $25.00 which is the best price I have seen.
I own an Osprey Kestral pack which came with its own raincover. I have found that cover to be so handy for the Kestral pack, I wanted one for my Talon 22. I bought the Extra Small size cover and it fits my Talon 22 Sm/M pack perfectly, with room to spare. It easily folds up into its own pouch, and even came with a separate mesh pouch, which I plan to use as a trail wallet, since putting the self pouch into the mesh pouch seems redundant. I haven't had to use the XS UL Raincover yet on my Talon pack, but if it keeps my Talon as dry as the Kestral cover keeps the Kestral pack, I'll never go on a hike without it.
I bought this for my aether 85 and I love it. It's light weight, easy to put on, and protects my pack from the rain perfectly it was a great investment and I would recommend you get one to.
Plenty big enough to cover my 85 liter Osprey pack, good quality, survived Philmont without issues. If you're determined you can even get it back into the tiny little carrying bag it comes in.
It definitely kept my pack dry when it needed to, though it's not as durable as I had hoped. I think the plus side to this is it packs down extremely small. Take your pick I suppose ;)It did survive two trips through checked-baggage on an International flight from CA to Europe without any rips but some decent scrapes that will probably become holes soon enough. I used it to completely cover my pack so that none of the straps would get eaten by conveyer belt machinery and destroy my beloved pack.
Size medium fits my Atmos 65 well. I used this to protect my straps when checking it at the airport.
I would have found it useful to know what size backpack - in liters the raincover was meant to cover. I think this one might have been a bit big, but that's better than too small.
It was nowhere big enough for my 65 liter pack even though it was advertised to fit up to 70 liter packs. It looks good and feels sturdy enough but I have to send it back for a larger size
It packs down to the size of a baseball and weighs just a few ounces, but on their smaller packs (I have the Talon 44), you have a lot of extra material. I cinched down the cord as much as possible, but would have liked to tighten it some more. It flaps a lot in high wind. I wish they made a cover for each bag, or better yet, an integrated rain cover.
Answer: no
