How to Choose the Perfect Freediving Mask
Discover how to choose the ideal freediving mask, avoid leaks, and improve comfort for every dive. Learn expert tips and find your perfect fit.
Unlocking the Best Freediving Mask for You
Finding the right freediving mask can feel as tricky as choosing a pair of shoes—until you know what to look for. With so many shapes, sizes, and features, it’s easy to invest in the wrong one. Whether you’re a seasoned freediver or just starting, the right mask can make or break your experience underwater. In this guide, I’ll help you navigate the sea of options, ensure the perfect fit, and avoid common mistakes.
Why the Right Freediving Mask Matters
Freediving relies on simplicity—just you, your breath, and the ocean. Yet, the wrong mask can disrupt this harmony. High-volume masks, typically used for scuba or snorkeling, require more air to equalize, leaving less for your ears and lungs. This can limit your depth and even lead to discomfort.
In freediving, a low-volume mask is essential. It minimizes the air needed for equalization, reduces the risk of mask squeeze, and conserves valuable oxygen for deeper dives.

How to Find Your Perfect Freediving Mask
1. Fit Is Everything
Every face is different, so the fit is key. Here’s a quick test:
• Hold the mask against your face without using the strap.
• Inhale slightly through your nose.
• If the mask sticks without air leaks, you’ve got a good seal.
💡 Pro tip: Smile with the mask on. If it lifts or leaks, it might not stay sealed during a dive—especially if you laugh underwater.
2. Consider Your Unique Features
Got a mustache? No problem. Apply a layer of Vaseline to create a seal or shave just below your nose.
3. Test for Comfort
Spend a few moments wearing the mask in the shop. Ensure it doesn’t press uncomfortably on your nose or forehead, especially for extended dives.
Low-Volume Masks: The Key to Depth
Low-volume masks allow you to dive deeper with less effort, conserving precious oxygen for equalization and staying relaxed. Here are some top picks:
1. Aqua Lung Sphera
• Ultra-soft silicone
• Wraparound lens for great visibility
• Perfect for deeper dives
2. Seac M70
• Low volume with a double-edged skirt for a perfect seal
• Great for both freediving and spearfishing
3. Mares Viper
• A snug fit that adjusts to your face
• Excellent visibility and a sleek, Batman-like design

Specialized Masks
Prescription Masks
Need corrective lenses? Tusa and Freedom Ceos masks offer customizable prescription options, so you don’t have to worry about losing contacts underwater.
Full-Face Masks
For snorkeling or those uneasy with submersion, full-face masks offer 180° visibility and comfort. Note: They’re not suitable for deep freediving since they don’t allow equalization.
How to Prevent Fogging
Mask fogging is a common annoyance for freedivers, but it’s easily preventable:
1. Toothpaste Trick
• Rub a non-gel toothpaste on the lenses, rinse thoroughly, and enjoy fog-free dives.
2. Lighter Technique
• Carefully heat the inside of the lens to burn off the factory coating, then rinse. Avoid this method for masks with plastic lenses, like the Aqua Lung Sphera.
3. Baby Shampoo
• Apply a thin layer, rinse gently, and you’re good to go!
Freediving with the Right Mask
When you’ve found the right mask, your freediving experience transforms. One student of mine switched to a low-volume mask and immediately felt the difference. She not only reduced discomfort but also achieved her first 30-meter dive—a new personal best!

Final Thoughts
Freediving is as much about preparation as it is about the experience. The perfect mask isn’t just about looks—it’s about comfort, fit, and function. Spend time testing and choosing wisely to ensure every dive is seamless.
