I can't say enough about how great these goggles are. We went on a family vacation a few weeks ago and got to test these out. My son loves that he can clip them together instead of having to pull them over his face. When you pull them over your face they tend to loosen up a little. The clip allows them to stay whatever length you set them to. They are anti-fog so he was thrilled about that. His old goggles always fogged up on him mostly because he doesn't let his air out slowly when surfacing. These goggles also have a comfortable nose piece. It can flex to any shape/size nose. I received this item at a discount in return for an honest unbiased review.
