My daughter wore these every time I took her out in the sun for extended periods of time. They seemed to fit really well, not too tight against her nose. They really weren't hard to put on, and once they were on they stayed put. They must have been comfortable because she never once tried to remove them. I would highly recommend this brand to other buyers, I even showed them to my optometrist, and he said the lenses were good quality. I have just ordered the Julbo Looping 3, which is a larger size since I liked the first ones so much.
