I love my LifeThreads masks! They are well made and look great! Seem to be built for the long run because the material is of a high quality. Sadly, I cannot use mine because they bend my upper ears forward like a Scottish Fold kitten. Sometimes the mask will occasionally slip off because of the bending. This is unfortunate, because the masks are still comfortable and breathable. I am not a large gentleman, either. I am 5-foot-7 and 160 lbs. If I figure out a way to modify them, I will eagerly put them back into my mask rotation.
