Jackpack - A lot of 'pack' things are pretty cool: Jetpack. Six pack. Rat Pack. Even Tetra Pak. And now the leader of the pack: Jackpack. The camera sling bags come in five different sizes all for different proportions of camera equipment. That's right, we even have sling bags for those who are well endowed.... So put on the Jackpack Sling Camera bag and keep both hands free for more important things than carrying. Like designing a jetpack. Or drinking a six pack.
