The fit is the best you will ever get, I assure you. I’ve used many goggles in the past and I always had to press them against my face to get a good seal. These feel like they are barely on but have a perfect seal. The waterproofing is like your typical goggles but the fit is far superior to anything I’ve worn. Not that I have a big nose, but most other goggles hit the bridge of my nose when trying to get a good fit. I’m on my third pair. I have a pool set and 2 for open water! The mirror/reflective goggles are awesome blocking the morning sun and you can see perfectly! I won’t buy another set of goggles from another company. The only negative review I will give, you have to be very very careful not to break the nose piece. It’s common and the goggle will be ruined. If you take good care of them, they will last. I broke my last set in a triathlon. Thank God I checked them before my next race because something happened to them in transition after my swim. When I went to rinse them in clean water, the nose piece was broken and the goggles were ruined. I hear this is common. My other two sets are still awesome!
