1. Have 3 layers so they're really functional. This also means you don't have to worry about wet spots.
2. They fit really well and all has a notch for covering the tip of the nose so they stay in place, no need to keep readjusting.
3. They're all First Australian made so they all have great designs.
4. Downside: Only two of the 11 masks I bought has writing imprinted on them: the Warrior Dreaming by Lorni Byland and another one that says AMPA. These info are minimalist and miscroscopic (AMPA one is actually huge), and are integrated as part of the design, so they don't really interfere with the designs. They help tell the story of each specific mask so I hope they all keep them next time. Better yet, they could include a short story on the inside of the mask to help confirm Google information.
