I am a regular swimmer, swimming 6 days a week for the past 4 years. I have umpteen goggles of different brands (Speedo, Tyr, Arena, Nabaiji), with different coloured lens suitable for different times of the day. This purchase is amongst the best I have made (similar one is Tyr Velocity Mirrored Goggles). Most suitable for swimming in bright sunshine, fits perfectly (no, I'm not a schoolboy, but a 55 year old male). I'd highly recommend this for anyone who gets irritated by the bright glare of the sun on water.
My son loves these goggles as not many children's goggles have mirrored lenses and he is the only one in his class to have them. The only thing he has complained about is they do fog up as they are supposed to be anti fog.
After trying a number of top branded swimming goggles for my sons', we have finally found some that they can both wear without either falling off or being very uncomfortable!!
The fitting was absolutely perfect. I have used it today. No leaking, no fogging. I fell in love with this google. Hope my wife will buy me another one for Christmas.
