Does the job for me
I bought a medium cover for a non-Dakine backpack. The fit is perfect, easy to put on and doesn't take up space in my backpack when not in use. It does the job keeping my items inside dry and I don't go on a hike without it since I live in Florida (it'll pour even when the sun is shining). Now if Dakine could come up with a product to keep my backpack straps dry and i'd really be a happy camper.
