Hollis M4 Frameless

Hollis M4 Mask – Comfortable Fit, Wide Underwater Vision

The Hollis M4 Mask brings together two essentials when choosing a dive mask: a comfortable fit and a clear view. Designed to fit a wide variety of faces, it offers excellent peripheral and vertical vision in a compact, low-profile design. Whether you are exploring a reef, keeping your buddy in sight or looking around a dive site, the M4 helps you enjoy more of your underwater surroundings.

With its frameless construction, silicone skirt and low internal volume, the M4 is a practical choice for divers who prefer simple, functional equipment. It packs easily, comes with an adjustable strap and includes a rugged mask box for storage and transport.

Wide Field of Vision

A good field of vision helps you feel more comfortable and aware underwater. The Hollis M4 offers generous peripheral and vertical visibility, allowing you to look to the sides and up or down with less restriction from a bulky mask design.

This makes it a useful option for enjoying underwater scenery while staying aware of your buddy and nearby surroundings.

Frameless Design and Silicone Skirt

The M4 combines a frameless design with a soft silicone skirt for a compact profile and comfortable contact with the face. Its shape is designed to accommodate a wide variety of faces, while the adjustable mask strap lets you fine-tune the fit.

As with any dive mask, choosing a shape that fits your face well is essential for comfort. The strap allows adjustment without needing to overtighten it.

Low Volume and Convenient Storage

The M4’s low internal volume means there is less space inside the mask to clear if water enters. Its low-profile construction also makes it easy to pack alongside your other equipment.

For divers looking for a spare mask, the compact design is convenient to stow when suitable storage space is available in their equipment setup.

Protection Between Dives

A rugged mask box is included to help protect the M4 when travelling to dive sites or storing your equipment between trips. Keeping the mask in its box also helps organise your dive bag and reduces direct contact with other equipment.
