Tropo refines the iconic ‘Aviator’ look of the past sixty years to create a modern classic.
Alutra Photochromic lenses are optimised for high contrast environments, such as flying and driving, where it can be extremely bright outside but where instrumentation is in deep shade. The photochromic element is activated by UV light and so rarely activates on an airliner flight deck due to the thick windscreens. UV penetration into other cockpits and car interiors will vary depending on the screen material; the sun-lenses will activate and adjust accordingly.
The frames are made from titanium, a strong, lightweight and corrosion-resistant metal. Beta titanium is used for the arms and it’s springy properties apply just enough pressure to keep the frames securely in place.
The nose pads are fully adjustable for a customised personal fit, and the ear tips grip without pulling hair.
The accessories that come with these sunglasses include:
- Crush-resistant, zip-up glasses case
- Microfibre polishing bag
- Additional non-slip nosepads
- Warranty, care and fitting instructions
