MountainsmithLumbar Pack Rain Cover

easy to use and keeps the pack dry. Like the little holder that it comes with so you can simply roll the cover up and carry it inside your pack when you're not using it. Because it's got elastic - good elastic - around the edges, I am able to use it with another pack by ll bean

I have been looking for a waterproof cover for my lumbarpack for years. This is perfect.

Fits perfectly over an Osprey Talon hip pack.

Great feature for pack. Knowing things will stay dry when the weather goes bad is great.
