Review (5/5): Comfortable
Significant other needed a face covering to return to work but didn't want something ear straps. It's a single layer of lyrica type material (slightly thinner than bathing suit material). You can see through it when held to the light. He says it's breathable, stays put and doesn't cause sweating. Overall pleased with comfort.
Came well packaged and shipped quickly. No strange or overwhelming odors like some new materials. It's not going to stop a virus but it does comply with his works new requirements.
