The frameless masks are appreciated by many divers for their low profile and the ability to fold them for easy transport, even fitting into a jacket pocket. Cressi's frameless design combines a high-quality silicone facepiece directly with a single lens for ultimate simplicity. The reduced internal volume allows for effortless clearing, and the buckles of the quick-adjust straps are integrated directly into the mask to ensure a flexible fit and low drag. Additionally, it is unbeatable in price, costing only about half as much as comparable goggles.
