When you carry a conventional photo bag by the handle or on your shoulder, over 50kg of pressure can be exerted on both sides. The simple but effective G:Stop! construction (patent pending) absorbs mechanical pressure. Lenses or cameras damaged by gravity are a thing of the past.
Moreover, G:Stop! Bags offer waterproof padded exteriors, padded dividers that can be rearranged, as well as many features not available on other bags. For example, an invisible interior membrane provides maximum water protection in the main compartment.
The membrane is only perforated by stitching on the underside of the zipper. High-quality materials, such as ballistic nylon make the black bags durable and extremely light.
