Input:
I am a lifetime swimmer, and have swam competitively for many years. These are my favorite goggles. Perfect fit, last long, don't fog up. I like that you can purchase them for only $12 on Amazon - they cost over $20 in stores. I am not picky about color, so I always order the least expensive color. Thank you, Amazon, for making this more affordable!
