Camera back pack with dual access - you can swing it around to the front while one strap is on your shoulder for quick and easy access to your equipment. Much like the lowepro slingshot, except that it has 2 straps instead of 1. After much research, I've decided this is the bag for me! Plenty of room for a dlsr with a mid range zoom attached, plus 2 or 3 lenses, a flash and other equipment.
