Here are the reasons Convenience Each BlueEagle Face Mask is packed individually in a sealed bag, making them easy to carry anywhere or share with anybody who might need a mask. They are always clean before use. Comfort To reduce cost, many producers use the same material for inner and outer layers. In contrast, BlueEagle uses an especially designed Thermal-Bonded nonwoven material on our inner layer to provide a soft and comfortable texture on your face. Flexibility Most masks in the market are made via one-way folding, which creates an obvious drawback: uncontrollable movement when talking. BlueEagle Face Masks are made by Ω folding, which provides great stretchability and helps the masks always stay where they should be. Breathability While it might seem that a multiple-layers design would make it harder to breath, this is not true. BlueEagle Face Mask has only 35 pa/cm2 differential pressure, while most fabric/cloth masks reach 70 pa/cm2.
