The Demetz mask strap is a practical accessory for face masks designed to prevent the loss of the equipment. It is a universal strap that can be easily attached to the mask and worn around the neck. This strap not only provides secure storage for the mask but is also equipped with a safety system that quickly releases the mask in the event of a strong fall. This ensures a high level of safety and comfort, especially in situations where the mask needs to be frequently removed and put back on. The mask strap is available in the classic color black and is suitable for all genders. It is an ideal solution for anyone who wants to keep their mask readily accessible without having to hold it constantly in their hands.
