Rated5out of5byfromperfect solutionThis is the perfect rain solution for a large pack. I have a large pack and lash my bag to the bottom of it and this rain fly covered it perfectly with a full pack in the Smoky Mountains where it seems to rain at least once a day.

Rated5out of5byfromREI Duck's Back Rain CoverI was looking for a backpack cover and this one was shown to me by the rep at the store. It was in the clearance rack. It is brand new and covers my huge military pack with no problem. It is lightweight and folds up very small.
