Dry gear makes a happy camper!  Since we all know that packs don't tend to be 100% waterproof, you need to be prepared with a good rain cover for your pack.

The popular Outdoor Designs Rucksack Rain Covers are now made by Podsacs, but they still feature superior quality and a terrific value.  The Podsacs Rucksac Raincovers pack light and small for the other 90% of the time you don't need them.  They feature an elasticated seal, with lightweight ripstop nylon and taped seams.  They even come in their own attractive stuff sack.
