Here are our fully adjustable children’s face masks with 2 layers of fabric. They are ideal for long-lasting wear thanks to their attachment system behind the head. They are equipped with a pocket allowing the insertion of a filter (not included). The elastics allow an easy adjustment adapted to head circumferences between 19 inches and 21 inches (48 to 54 cm). *For hygienic reasons, no mask is exchangeable or refundable.
