A good mask.
I ordered a second mask from Bioly at the beginning of February. The delivery took a lot longer than it should have, but this appears to be the fault of the courier not Bioly Mask. I understand Bioly are a small team so the replies to emails are a little slow, but they are very thorough when received. I can certainly recommend the masks they make, and they do reduce my spectacles steaming up essential as I wear them all day.
