The source gives an internal-volume figure and several coating claims. Those numbers are not a fitting result. Ask for the current manufacturer instructions and the exact selected lens variant, then compare the skirt shape and nose-pocket access in person.
A mask is worth comparing on your face, with attention to the nose pocket, upper lip and space around the eyes. A frame that looks generous in a photograph can still press in the wrong place. Bring a comfortable existing mask along as a reference, and check whether the strap and buckles are accessible with the rest of your equipment.
Lens layout gives you a useful way to narrow the shortlist, but it does not predict comfort. Single lenses, divided lenses and side windows offer different views. Ask about the precise lens treatment and replacement parts for the model you select; similar names can cover different versions.
It identifies a treatment that should prompt a model-specific care check. Follow Gull’s instructions for the exact lens before using cleaning or defog products, and ask a dealer if the treatment is unclear. Do not assume that a preparation method used on untreated glass is suitable for this version.
Try the mask with help from a dive shop or instructor, and pay attention to pressure points as well as the seal. Check the nose pocket and space above your upper lip. Tightening the strap is not a useful solution to a skirt shape that does not suit your face.
Check the instructions for the exact lens before using a cleaner or defog treatment. Coatings and attached films can need different care from untreated glass. Rinse and protect the mask during transport, and keep the skirt and strap from being crushed beneath heavier equipment in your bag.
Read the care guide, then follow the instructions for your exact equipment.
