24/7 Traffic Collection Sling camera Backpack in good condition - This was made by Adorama as a limited release, Adorama is on the forefront of camera bag development, and also created the Slinger bags which are very highly rated. 

Zippers work great, bag is clean - I only used this a couple of times as I prefer a shoulder bag or small holster bag
