Correct measurement instructions for simple sea masks

Classic sea masks are more flexible due to the smaller contact surface with the face. They do not have strict measurements and are usually One Size that fits most adults. However, some manufacturers provide sizes. Sizes based on face centimeters mainly apply to full face masks.

Size - Age Range - Notes

• S: 12+ years - For small or narrow faces (e.g. women, teenagers, people with small body structure)
• M: 12+ years - Regular fit for adults (usually referred to as "One Size")
• L: 12+ years - For wider faces or pronounced facial features

The above measurements are approximate and may vary depending on the brand or face shape. Check the manufacturer's specifications, as many masks state the size or the maximum face size they cover.
