Input:
These swim goggles are the best I have used. I used it for a college swimming class - twice a week for 3-4 months. They rarely fogged and rarely leaked water, which was important to me in a learning environment - I needed to not be distracted by my goggles or need to constantly take them off in class. I would definitely recommend these - they really held up under constant use.
