Updated November 2026

Looking for a mantis full face dive mask but unsure which model fits your face, your dive style or your comfort level? This guide compares seven full face masks from the Mantis line and related models, using manufacturer specifications, brand reputation and common owner feedback as the main selection criteria. Each pick is judged on fit and seal, field of view, breathing design, build quality and the kind of diving it suits best. The goal is to help you narrow the field before you buy, not to declare one winner for everyone.

Buying Guide

Intended use: scuba, free-diving or snorkeling

The biggest factor is what you plan to do. Scuba-rated masks are designed to work with a regulator and tank, while free-diving and spearfishing masks are built for breath-hold work and may not be suitable for compressed air. Snorkel-oriented masks trade some diving features for a wider view and easier breathing at the surface. Check the manufacturer’s stated use before you buy, and never assume a mask is safe for scuba because it looks similar to one that is.

Fit and face shape

A full face mask only works if it seals across your whole face, including the forehead, cheeks and jaw. Lie down, place the mask on your face without the strap, inhale gently through your nose and see whether the seal holds. A narrow face may leak on a model built for wider faces, and a broad face may feel pinched on a compact frame. Women with smaller facial structures often find that a lower-volume design feels more stable.

Field of view

Field of view varies a lot across full face designs. Panoramic models give you a broader sweep of the reef or surface, which helps with navigation and awareness. Confirm the stated viewing angle in the listing and consider whether you value peripheral vision or a more compact, focused view.

Breathing design and dead space

Internal volume affects how much air you need to clear the mask and how easily you breathe. Lower-volume designs are often preferred for working dives. Check whether the mask includes an air intake or an octo attachment, and confirm that the arrangement matches your regulator setup.

Lens clarity and glare

Clear skirts let in more natural light, which some divers like for recreational exploration. Darker skirts reduce reflections and can feel more comfortable in bright conditions, though they also limit light. Think about where you dive most often and how much light you usually get.

Build quality and durability

Look at the frame, skirt material and hardware. Silicone skirts are common on full face masks and generally tolerate salt water well when rinsed. Ask whether replacement parts are available from the manufacturer, since a mask with accessible spares can last longer. Rinse with fresh water after every dive and store the mask out of direct sunlight.

Care and maintenance

Full face masks have more parts than standard masks, so routine care matters. Rinse thoroughly, let the mask dry fully before storage and inspect the seal for cracks or stiffness. Replace worn seals promptly. Manufacturers typically publish care instructions, and following them is the simplest way to keep the mask performing well.

FAQ

Is a mantis full face dive mask safe for scuba diving?

Some full face masks are designed for scuba and others are not. Check the manufacturer’s stated use for each model. Scuba use with a regulator requires a compatible design and proper training. If you are unsure, consult a certified instructor before you dive.

How do I know what size full face mask to buy?

Sizing is less standardized than with standard masks. Try the mask on dry, check the seal without the strap and compare the manufacturer’s dimensions to your face. If possible, test the mask in a dive shop before buying.

Can I wear glasses with a full face mask?

Standard glasses generally do not fit inside a full face mask. Some divers use prescription lens inserts, which are sold separately for certain models. Check compatibility with the specific mask before you buy.

Do full face masks fog more than standard masks?

Fogging depends on the lens, the skirt, your breathing and how the mask was prepared. Many owners report that a proper anti-fog routine and a good seal help more than the mask type itself.

How long does a full face mask last?

Lifespan depends on care, storage and frequency of use. Silicone components wear over time, and the seal may stiffen or crack. Inspect the mask before each dive and replace worn parts as the manufacturer recommends.

Can children use a full face mask?

Most full face masks are designed for adults. Check the manufacturer’s age guidance before buying, and always supervise younger users in the water.

Is a full face mask better than a standard dive mask?

It depends on your goals. Full face masks offer wider coverage and can suit certain work or snorkel-style uses. Standard masks are more common in certified recreational scuba and are simpler to learn with. Choose the design that matches your training and dive plan.

Conclusion

The Riffe Mantis 5 Mask works as a versatile starting point for recreational and spearfishing use, while the Riffe Mantis Mask for Diving and Spearfishing suits a more specialized hunting focus.
