Revo has partnered with Bear Grylls, the British adventurer and television personality, on a line of co-branded sunglasses targeting active people. The sunglasses are made of an innovative flexible material that is said to be almost unbreakable. The collection features the signature Revo lenses, which are said to offer an optimal visual experience for outdoor enthusiasts. The line of sunglasses is due for a pre-launch in autumn 2018, ahead of a full launch in spring 2019. The sunglasses will be sold at www.beargrylls.com, www.revo.com, optical stores, outdoor retailers and travel retailers. Revo was founded in 1985 by a NASA optical engineer, Mitch Ruda. Revo sunglasses were first created with lens technology developed by NASA as solar protection for satellites. Revo is a wholly-owned subsidiary of B. Robinson.
