I have worn out countless swimming goggles. I always had the same problem that the side ran into the eye through the edges while descending water. Constantly I had to interrupt my swimming lanes to rummfummeln glasses empty, or at Einstellgummi. With these glasses I'm finally happy. She sucks comfortably with the wide silicone edge to his face and holding really tight. Even the setting of the head is very comfortable thanks to the rubber quick release. Maybe the glasses looks a bit bulky in the face, but that's me in terms of this gained Komort`s really care. With Amazon übrigends get much cheaper than in stores.
