The side lenses of the panoramic 3 are precisely fit to the main lens for a nearly uninterrupted field of view. The result is a mask that allows maximum light and feels as open as the ocean itself. Quick-adjust mask strap buckles provide a secure fit and are easy to manipulate, even while wearing gloves and a high quality Silicone skirt provides an excellent seal for most faces. The panoramic 3 also represents an excellent value.
