I bought four of these as because I wear hearing aids & masks with elastic headbands don't play nicely. £4K (yes - you read that right, that's what they cost!!) worth of hearing aid flicking onto the tarmac in Sainsbury's car park is not great. Add glasses as well, and there's a lot of competition for the space behind my ears.
I double these over so I have two layers of material covering my mouth and nose - I believe reduces the chances of me passing Coronavirus on to you.
I have a big head, so these are a little tight on my nose. My more expensive Buff is better in that regard. But as I am not using them as intended I can't really complain - if I had them round my neck for warmth, on my head for sun protection or on my wrist as a sweat band they would be fine.
If I need to wear a mask for a long period I switch out to a home made one with elastic & take out my hearing aids.
Whether I'm promoting Autism Awareness is another matter. I'd be happy to do that but I had no idea this pattern was a thing for that and I bought them as they were tyhe least girly option.
In summary, good product - happy to recommend.
