OMG!! These are a game-changer for me! Upon arrival, I thought that these would not work because there was a strange-sized nosepiece on the glasses. However, once I selected one of the other nose pieces hidden beneath the styrofoam, then fitted the straps, the fit was comfortable-- not tight- but PERFECT!! The only thing left to do was to test them in the water. I went to the pool and performed as normal. Guess what? No leaks, no fogging, no tightness, and the peripheral view was good. I did not have to get accustomed to the view at all. Just cut the straps that flop because they are so long but not too troublesome. [No one's head is this big. LOL!!!!] One key point for those of African descent, these scans work for us as well. You may just have to change the nosepiece that is positioned on the glasses upon arrival. The nosepiece marked "+" was especially a good fit for me. Good job Magic5 folks. I recommend these glasses and will order another pair -- maybe the smoke black. Oh yes. I did not notice the silicone swim cap when I purchased the blue lens and black strap pair, but I will certainly purchase one of the silicone swim caps as well. I think they may only be purchased with the purchase of the glasses. Nonetheless, buy these swim goggles folks!
