Brilliant masks are exactly that! I've bought several of them now so I can have one in my pocket, one to wash and at least one lost somewhere in the house. They fit well, aren't as claustrophobic as some and don't scratch like the disposable masks. The only downside I have found is that with repeated bending of the nose strip, these can break over time. The easiest solution is to buy a pack of aluminium strips and with a minor bit of unpicking and sewing up again, the masks then carry on as good as new. Would love to see even more fabric designs available as the choice does seem a bit limited.
