This product is very thin and strong. There is no problem with the tightness of rubber. However, since it sweats when wearing for a long time, it may be that moisture inside does not go out. I think that it is a very good thing except this one point. I think that it is the best thing I have ever used.
For preventing hair contamination, I am wearing, but even if I wear it, rubber and feeling of pressure are not bothersome. Because it is not bulky, put it in your work clothes pocket, you can use it anytime convenient.
