The frameless design makes it a great choice for a number of reasons. Frameless masks are low volume masks, which is a popular feature for freedivers and makes the mask easier the clear of any water that came in.
Frameless masks sit closer to the face which enhances the field of vision, making the Scubapro Frameless a great choice for people looking for a mask that is great for visibility.
The buckles on the mask are easy to loosen and tighten, and are placed directly on the skirt. This means it's easy to fold flat the mask and place it in a BCD pocket for example.
Only available in Black/Black variant.
