If you are looking for a pair of super-comfortyable, ultra-lightweight sunglasses for sport, these are an excellent choice. Mine last pair eventually got scratched - hardly surprising given how i treated them - and all i wanted was a like for like replacement. i couldn't be happier.
These sunglasses are light, flexible and don't impact visibility like some sunglasses. A bit pricey but you do notice the difference compared to cheaper ones
