The Chronos is Michael Phelps's preferred training and "workhorse" goggle. It's a no frills goggle and our modern take on the traditional Swedish-style goggle. For the Chronos, we used our patent-pending Geoplex lens technology to offer distortion-free, superior vision in each direction. And for your long training days, you'll appreciate our Softeril micro gasket for better comfort and watertight fit.
