Many of you are planning our spring and summer backpacking trips, so I thought I'd share this with you. The Pac Safe 85 can be used to keep you bag or backpack safe. It's a simple web that encompasses your pack(or suitcase, purse, etc.), so no one can open the zippers (very easily) and get into your pack. This is a great security measure to put over your bag while you're traveling. Not on the plane, but once you arrive.
