I have tried many different types of masks. These masks are by far the best. The fabric is of good quality. The insert for a filter provides the required 3 layers of protection necessary.
The wire nose piece bends perfectly to allow the wearing of glasses on top with no fogging at all. I wear a mask for 6 hours at a time and find this one comfortable. The ear straps are adjustable, ensuring an exact fit. I am so glad to have found these masks. They are pretty too.
The mask chain was of much higher quality than expected. It is not a flimsy chain. It is substantial, but not too heavy. I have purchased 4 just in case they should ever become unavailable.
This chain is perfect for having my mask at the ready.
