Between the padded strap, and the pivoting shoulder strap to carry how you want (shoulder bag, cross body or sling carry) this sling was designed for maximum comfort. The back of the sling has an EVA foam formed back panel for comfort and air flow. There is a roller luggage pass-thru to give your shoulder a rest while traveling. On the front and bottom of the sling, there are external molle straps if you need to carry more like a tripod or jacket. The sling fits perfectly inside the Camera Bag 35L.
