The Digital Holster 40 camera holster bag holds a deep body pro size DSLR with attached zoom and can be worn on a belt or over the shoulder. A ‘pop-down’ zippered base allows the bag to expand to accommodate a 70-200/2.8 with hood reversed. It's amply padded, to provide good protection but with minimal bulk. The top flap opens away from the body to give quick unobstructed access to the camera. Stretch pockets under the lid and on the front take small accessories like cards, spare battery and lens cap. Like all Think Tank bags it has metal hardware and YKK RC Fuse zippers for long lasting durability.
