Bose - Montura Tempo

Comfortable. And secure.
They wouldn't be performance sunglasses if they didn't stay put. That's why we precision engineered Bose Frames Tempo to feel like they're a part of you, from the soft, silicone nose pads to the flexible temple grips to the custom spring hinges that hold just tight enough to stay secure and just light enough to stay forgotten. Because on the 15th kilometer, all you should feel is your runner's high, not your sunglasses.

Blood, sweat, and tears. Rain, too.
On the path to perfection, you face it all. Your sunglasses do, too. That's why these IPX4 water-resistant sport sunglasses were designed to survive the elements. The polycarbonate polarized lenses are scratch- and shatter-resistant. The TR-90 nylon frame is rugged and durable. And a specially designed acoustic mesh in the ports helps keep out water and debris.

Nothing in or on your ears
That's the difference. It's a revolutionary Open Ear Audio™ experience that frees you from headphones so you can stay aware of your surroundings - traffic, pedestrians, whatever you run up against when exercising outside. And when you need more motivation, just turn it up. With specially designed Bose speakers, one embedded in each temple, Bose Frames Tempo play louder and deeper than all other audio sunglasses so you can feel the music, and the endorphins, even over the rush of the wind when cycling at speeds of 25 mph.

Switch lenses. In seconds.
Interchangeable sport lenses make Bose Frames Tempo multi-sport ready. Swap lenses in seconds to match your current terrain and lighting conditions. Road Orange, Trail Blue and Twilight Yellow.
