We sell the ION Functional line of sports sunglasses.

Whilst there are numerous brands on the market that have the wrap around straps to keep the glasses on your head ION has developed a unique 'key' style strap end, so the elastic headband can easily be attached or removed, basically when you take the strap off you have normal looking sunglasses that you can easily wear home, to the shops or other important fashion events. These really are nice fashionable sunglasses that you can wear kitesurfing or windsurfing, not mini goggles.

We can personally vouch that if you do the strap up tight they will stay on your head for all but the most radical moves.

If you are thinking of putting prescription lenses in we do know that this is possible.
