the bathing cap fits quite well. I always have the problem that when swimming without a cap I get water in the ears, which then stops for hours. The well has prevented the cap. ir personally the cap was a bit too big for head circumference 57 cm. it is then but always slipped up while swimming and his ears were free again. Very annoying: use after only 5 times is simply a part of the cap pulled down as I wanted this winding. I at that time had longer hair, I was also relatively cautious when pulling. This points to poor quality and at a conversion anyway then you have a bad hand. Because of this, only 2 star, I would not buy this bathing cap, because my life is but then too short for the money.
