Greatever Full-Face Snorkel Mask G1

Highlights

If you want to breathe through your nose or mouth without switching between a separate mask and snorkel, this full-face design is built around that simpler setup. If your priority is a more traditional, minimal snorkel, its larger face-covering format may feel like more gear than you need.

The Greatever G1 has a claimed 180-degree panoramic view, with flat, clear lenses intended to limit underwater visual distortion. Its separate inhalation and exhalation paths and three independent air channels are presented as features to support airflow and reduce fogging and the rebreathing of exhaled air. Those are design claims, not a substitute for following the product’s instructions or using a mask that fits properly.

A silicone skirt is intended to seal around the face, while the mask folds for packing and includes a removable camera mount and travel mesh bag. That combination suits a beach trip where you want to snorkel and keep a small camera attached, rather than carry a separate mask-and-snorkel setup. One limitation to keep in mind: the fit depends on the mask sealing against your face, so the listed size guidance matters.

Fit and sizing

Choose a size using the measurement from the bridge of the nose to the bottom of the chin. The listing assigns S/M to measurements under 4.72 inches and L/XL to measurements over 4.72 inches. It does not specify what to choose at exactly 4.72 inches, so the provided guidance does not resolve that borderline measurement.

A solid pick if that measurement clearly places you in one of the two size ranges and you prefer breathing through either your nose or mouth while snorkeling. It might not be a great match if you want a conventional snorkel, or if you cannot get a comfortable seal with the available sizing. The product is described for adults, men, women, and youth, but the measurement—not those broad labels—is the useful starting point for choosing a size.

Tips for day-to-day use

Before heading into the water, measure carefully and make sure the skirt sits evenly around your face. For a practical first outing, try the mask in a calm, shallow setting and pay attention to whether it stays sealed as you look around and breathe. That gives you a chance to notice a fit issue before relying on it for a longer snorkel.

The foldable design and included mesh bag are useful when packing for a beach day, while the removable camera mount can help keep a compatible camera attached during a swim. The listing does not name camera models or describe how to install one, so check those details before counting on the mount for a particular setup. Rinse and care instructions are not provided in the product information.

Questions before you buy

Can you breathe through your nose with this mask? The listing says the full-face design allows breathing through the nose or mouth while snorkeling.

Does it include a camera mount? Yes. The product description says the mount is removable, it does not identify camera compatibility.

What warranty is listed? The seller description states a one-year warranty and mentions replacement or refund service. It does not explain the conditions, so check the warranty terms before purchase.

Should you buy it?

This mask makes the most sense if you want a foldable, full-face snorkel setup with a wide stated field of view, a camera mount, and sizing based on a simple face measurement. Its channels and anti-fog, anti-leak features are central to the design, but the listing alone cannot establish how well the mask will seal on your face. Choose it when the measurement fits the stated range and you prefer this all-in-one style, consider a traditional mask and snorkel instead if you want a simpler format or would rather select those pieces separately.
