Multiple lenses, different frames, same sunglasses.
If you change out the Bliz Women's Tempo Small Face Sunglasses' lens, and then replace the temples with the goggle strap, is it still the same Tempo Sunglasses? All-around active adventurers, the Tempos are the lightest pair of sunglasses in the Bliz lineup. The Unbreakable Polycarbonate lenses are ten times more impact-resistant than standard plastic or glass lenses. There are grippy pads at the temples and nose that you can adjust for a secure fit, and Bliz added a top bar that wicks sweat for extra comfort. Since Bliz included a goggle strap and a bonus lens, it's almost like you're getting two sunglasses for the price of one.
