molecule, bacterium and virus efficiently so as to prevent the
dust, water molecule, bacterium and virus from entering the thin
film layer 1 so that the thin film layer 1 can isolate most of the
harmful substances to protect the user's health from any danger of
infection. In addition, the thin film layer 1 is made of e-PTFE,
TPE, TPEE, COC or FRP so that the thin film layer 1 is soft and has
a warming effect to provide a comfortable sensation to the user.
Further, the thin film layer 1 is made of e-PTFE, TPE, TPEE, COC or
FRP so that the thin film layer 1 is waterproof, resistant to
chemical agents, resistant to high and low temperature and is
easily cleaned. Further, the thin film layer 1 has a very small
thickness and has a plurality of pores 11 so that the thin film
layer 1 has a better ventilating effect to make the user breathe
easy and well. Further, when the loop-shaped straps 2 are put on a
