Hollis M4 Diving Mask Black

The Hollis M4 Diving Mask Black is a top-of-the-line ultra-low volume mask that provides excellent comfort and vision. The frameless mask design makes it a great choice as a primary mask or backup mask.

Low Volume And Increased Visibility
The mask's low profile ensures a perfect fit for a wide range of face shapes, while its superior peripheral and vertical vision provides an unobstructed view of the underwater environment.
​

Frameless Silicon Skirt
The frameless black silicon skirt is designed with a double feathered edge that ensures a perfect seal against the face, while the wide split strap design ensures that the mask stays securely in place during even the longest of diving sessions.

The M4 diving mask is easy to adjust, thanks to its easy-adjust buckles and strap, and the large one-handed nose pocket makes ear equalization a breeze. The Hollis M4 comes with a rugged mask box and an adjustable mask strap for easy storage and transportation. 

Single Lens
The M4 features a single-tempered glass lens that is both safe and optically excellent. 

The Hollis M4 diving mask is an outstanding choice for any diver looking for comfort, safety, and superior vision.
