We have designed the masks so that that you can wear them many ways. You can use tie to tie them around the back of the head and neck or else tie them as loops around the ears.
For ease of use / adjustability we have introduced the AUQUA Toogles which can be put onto the end your ties. these toggles are sold separately and you can place the toggles on the strings either so the mask can do up around the back of the head or around the ears as ear loops.
