Pack Rain Cover

Excellent quality
This is the highest quality backpack cover I have seen (it's also the heaviest). However, it is not large enough for my 6550 cu in Kelty backpack. So, I went with an Outdoor Research Extra Large lightweight pack cover. The OR did fit with room to spare so it's by far the largest cover out there (I did quite a bit of research). I narrowed all of them down to two and had to order both and return the one that didn't fit. In spite of the increased weight I would have kept this cover if it would have fit. Seems like it would last a very long time. The OR is closer to parachute material so won't last as long.

Excellent fit over fully loaded BMG pack
Fits well over fully loaded BMG pack (6500ci), even with 2 Carcia bear cans attached to the outside. Compresses nicely into it's own sack.

nice rain cover
The (large) rain cover worked great with my 85L Osprey pack with room still if I had to put items on the outside of the pack. The picture isn't the same as the product however. I gave it four out of five because it still felt big on my fully loaded pack. Otherwise a great product kept my pack dry and clean.
