Frequently Bought Together
The DinoSon device allows you to tie a 3-ply mask behind the head with an earhook fastening system. The advantages are twofold:
1) Reasonable reinforcement of the tension on the elastics to ensure a better positioning of the mask on the face to improve the fit and the filtration of the inhaled ambient air.
2) Minimize irritation of contact areas behind the ears by repeatedly wearing masks.
