Children's Masks

The classic children's sea masks, whether single-lens or double-lens, are more flexible due to the smaller contact surface with the face. They do not have strict measurements and are usually One Size within an age category (e.g. Kids 3–6 years, Junior 6–12 years).

Sizes based on face centimeters mainly apply to full face masks.

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