Adventurer Bear Grylls has partnered with performance sunglass brand Revo to develop a co-branded range of products.

The sunglasses are made of an ‘almost unbreakable’ flexible plastic material, featuring signature Revo lenses for an outdoor adventure lifestyle.

Grylls said: ‘Revo are quite simply best in class and have put so much time and research into their lenses, as well as building the ‘almost unbreakable’ tag line. It would have been “totally unbreakable” but I had one pair crushed to bits in a rockfall where a two‐ton boulder landed on top of them. So “almost unbreakable” it is.’

Menrad Optics has the distribution rights for the Revo brand throughout Europe. A pre‐launch for the collection this autumn will be followed by a full launch in Spring 2019, both online and through optical retail stores, a statement said.

Cliff Robinson, president of Revo, added: ‘I am so honoured to be a part of this new partnership. Aside from being a long‐time fan of Bear’s, I couldn’t be happier that Revo lenses are his first choice for his rugged outdoor lifestyle. If they are good enough for Bear, they are good enough for all of us “regular people” too.’
