Hollis M4 Mask Review

I was looking for a good scuba mask that would be easy to use and comfortable. I had never used a mask before, so I wanted to make sure I got one that was well-reviewed by other users. This Hollis M4 Mask had great reviews, so I decided to give it a try.

It has been great! It is super light, which makes it easy to put on and take off. The frame is also flexible and soft, so it does not cut into my face while I am wearing it. It also lets me see clearly underwater, I can see everything around me clearly without any distortion or fogging up of my vision.

I have tried this mask with both snorkeling and scuba diving and found that it works really well both ways. It has a large viewing area, so you get a clear picture of what is going on around you while also being able to see clearly below the surface of the water with minimal distortion from the lens itself.

The mask comes with an adjustable nose clip so you can customize how tightly it holds onto your face without cutting off circulation or causing pain; however, if you prefer not to use one at all then there are two other options for adjusting how snugly it fits around your head: there are two types of head straps available

My favorite part is how easy it is to adjust: you just press on the sides of the lens until you get the right fit for your eye shape! It is really simple once you get the hang of it, but do not worry, I did not have any trouble figuring out how to do it myself either way.


The Hollis M4 mask is a frameless scuba diving mask, which means that it doe not have the traditional frame around the eyes. The advantage of this design is that it allows you to see more of your surroundings and allows you to use prescription lenses without having to worry about fitting them into a frame.

It is made from hypoallergenic silicone, which means that it is free from any toxic chemicals or irritants. It also has a very soft seal, which reduces pressure on your face and helps make the mask more comfortable.

The M4 mask comes with an adjustable strap that makes it easy for anyone to fit the mask for comfort and optimal performance.

Hollis M4 Frameless Diving Mask Design

The M4 dive mask has been designed with comfort in mind; it has a soft silicone skirt that helps keep water out and prevent it from leaking around your face. The skirt also helps reduce pressure points on your face when diving deep underwater which can cause discomfort or even pain after long periods of time. Another feature that makes this scuba diving mask so comfortable is its quick-release buckles. These buckles allow you to easily remove or put on your mask without having to fumble around. You will not fumble with straps or clips which can be difficult when underwater during dark conditions.

Low Volume and Adjustable Strap

The Hollis mask is designed with a low-profile skirt and an integrated purge valve. Because of this it stays in place while you are diving or swimming underwater. The skirt also has an anti-fog treatment built into it to keep your vision clear when you are underwater!

This scuba mask also comes with an adjustable strap system that allows you to personalize your fit even further than just adjusting the nose bridge. You can tighten or loosen the straps as needed without worrying about them coming loose during use or while traveling around town between dives!
