Fits just fine

I've used it several times

I used the large cover with an Osprey Aura 65 and had lots of room. It kept everything dry through multiple days of rain and then was quick to dry as well. It is a little difficult to cinch up the draw string round the pack, but not that bad, therefore 4 instead of 5 stars. The little integrated bag is handy.

Referee backpack rain cover

I've put it through the wringer

I bought this to use as a rain cover for my referee backpack and it does the job. when there is rain in the forecast I pack this in my backpack and have it ready if I need it. The material is great at covering my backpack and is comfortable to be left on the backpack and worn. I just wish I would have ordered a size XS instead of a small one. The cover has too much extra space and is only necessary when I need to take my referee jacket and track pants off and keep them dry.

Don't believe the size description

I returned this product before using it

They say size large fits 60-100L. I mean, it will fit, but not if you put anything inside your pack. This wouldn't even fit my 55L pack
