Reversible. Choose your own lining. Childrens and Adult sizes. Stretchy ear loops, can be tightened by tying a knot or choose adjustable lycra head/ear straps.
The three pleats and firm cotton allows the mask to sit in front of your mouth without going inside. The cotton dries quickly from your breath. This is my favorite mask so far. I use it to workout and I am very happy with the new ear loops. The mask is reversible.
