pretty versatile if you move your mask on and off your face [SEP] for the most part i like this product there are a few things that would make this a star review for me personally my personal things don t take away from the quality or versatility of this product in general and for the masses this probably will be exactly what you want and need for me the extension hook holes that hold on to the top straps could be a teeny tiny bigger and a smidge more stiff tho help holding it in place better the surface area around the mouth and nose could be bigger not that i have a big mouth physically but my smile is when i smile the edges of my mouth touch and go passed the bracketagain none of these take away from the quality and versatility of the mask bracket
