The Quick-Seal-Closure on the Aqua Cam, in combination with the roll-top, keeps your gear dry and dust free. The bag is never the less quick to open and close. The Aqua Cam can be carried as a shoulder bag, as a waist bag, or with the ORTLIEB Camera Harness System (optional accessory) which makes sure that your camera bag remains firmly attached directly to your body, and frees your hands for other activities.
