A durable hat, slightly thicker than most swim hats yet not bulky at all, it just makes it feel more comfortable and less flimsey. I am a regular lane swimmer with very long, think curly hair (down passed the middle of my back). I have tried the Speedo long hair cap but prefer this Maru one for comfort. With being less flimsey that the Speedo hat, it sits more comforably and is easier to put on withouit the fear of sticking my thumb through it. It stays in place better too. It is the second one I have bought after about 25 years of swimming.
