OakleyMsk3 Anti-fog Face Mask, Black- 1 Count (Pack of 1)

Q: Is this mask one size fits most or it fits all, I gave a midterm face , & will it fit a small face

It will fit a sm-med size face.

Q: How do you pack it when not needed? Is it squishable or would that damage it?

It is squishable, would probably fit in the back side pocket of your jeans. However i prefer to just hang it from the straps where I can because of the silicone material that surrounds the mask - just to maximize durability, not sure how it would take repeated bending/folding
