This bag fits a DSLR camera with attached lens and one extra lens. Body material is a composite of rubberized fabric and inner tube. Sandwich between the waterproof fabric lining is a 6mm foam padding. There are two secured exterior pockets in front and back to contain accessories and batteries. Expandable roll top opening is a convenient feature for extra space. The 7cm x 40cm strap pad is ultra-wide to ensure comfort from a heavy load. A small ring at the back is a provision for small carabiner hooked to your belt loop to keep the bag from swinging around as you shoot.
