Is PTFE bubble point membrane waterproof and breathable?

Regarding whether the PTFE bubble film has waterproof and breathable properties, in fact, the bubble film itself has countless interconnected micropores. The pore diameter is very fine and can only pass through water vapor molecules with a particle size of about 0.1nm. Any raindrop or water droplet is too large to pass through.

In this way, water vapor emitted by the human body can effectively diffuse outward through the pores, while water droplets cannot penetrate inward, thus achieving a waterproof and moisture-permeable effect.
