2. Choosing the Correct Size
Proper sizing is crucial for comfort and to prevent water leakage. To determine your size, measure the distance between the bridge of your nose and the bottom of your chin with your mouth closed.
- XS: Less than 10 cm (3.9 inches)
- S/M: 10 cm to 12 cm (3.9 inches to 4.7 inches)
- M/L: 12 cm to 13 cm (4.7 inches to 5.1 inches)
- L/XL: More than 13 cm (5.1 inches)

3. Attaching the Snorkel
Align the snorkel tube with the opening at the top of the mask. Push firmly until it clicks securely into place. Ensure it is fully seated to prevent water entry.
4. Adjusting the Straps
Place the mask on your face. Pull the elastic straps over your head. Adjust the straps evenly on both sides to achieve a snug, comfortable fit. The silicone skirt should seal completely around your face without excessive pressure. Avoid overtightening, which can cause discomfort and leakage.

Operating Instructions
1. Wearing the Mask
Once adjusted, ensure your hair is not caught under the silicone skirt, as this can cause leaks. The mask should feel secure but not uncomfortably tight.
2. Breathing
The Easybreath mask allows for natural breathing through both your nose and mouth. Breathe calmly and steadily. The dry-top system at the end of the snorkel tube prevents water from entering when submerged or hit by waves.
3. Field of Vision
Enjoy an expansive 180-degree panoramic view. The shatterproof polycarbonate window provides excellent clarity and safety.
4. Water Drainage
Should a small amount of water enter the mask, it is designed to drain out through a purge valve located at the bottom of the chin area when you lift your head out of the water. A slight tilt of the head can assist in drainage.

Maintenance
1. Cleaning
After each use, rinse the mask thoroughly with fresh, clean water. For a more thorough cleaning, wash the mask by hand with a mild washing-up liquid. Rinse all soap residue completely. Do not wash in a dishwasher.
2. Drying
Allow the mask to air dry completely before storing. Avoid direct sunlight or excessive heat, which can damage the silicone and polycarbonate materials.
3. Storage
Store the mask in its original net bag or a similar breathable container to allow air circulation and prevent moisture buildup. Store in a cool, dry place away from sharp objects and chemicals.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Mask leaks water | Improper fit; hair caught under skirt; snorkel not fully attached. | Re-adjust straps for a snug fit; ensure no hair is under the skirt; check snorkel connection. |
| Mask fogs up | Temperature difference; improper cleaning. | The mask is designed with separate breathing and viewing chambers to minimize fogging. Ensure proper fit. If fogging occurs, rinse the inside of the mask with a mild anti-fog solution or baby shampoo before use. |
| Strained breathing | Improper use; physical exertion; snorkel blockage. | Ensure you are breathing calmly and not over-exerting yourself. Check the snorkel tube for any blockages. Remember, this mask is for light surface snorkeling, not intensive activity. If breathing difficulty persists, remove the mask and seek fresh air. |
