Description
STRYVE II Photochromic Pro is a sport sunglasses model with an PHASE™ photochromic lens, designed for cycling, running, trail and all outdoor sports.
The PHASE™ photochromic lens automatically adjusts its tint to ambient light in real time. It darkens in the sun and lightens in the shade, without any action from you. One lens for every condition: dense forest, full sun or overcast skies.
The 6.3 lens offers a wraparound profile and a wide field of view. Peripheral coverage protects against wind, insects and debris. Full UV400 protection. All lenses are interchangeable. Photochromic sport sunglasses to keep you ready for changing weather.

The treatment is built into the polycarbonate and selectively filters specific wavelengths of light. These are the wavelengths that make similar colours difficult to distinguish. By reducing them, the lens creates more separation between tones that would otherwise look alike.
The result: terrain details become easier to see. Roads, shadows and vegetation stand out more clearly. It is not a colour change. It is a clearer view of what is already there.

Each SPEK frame accepts multiple lenses. Change them to suit the light, terrain or season.
The mechanism holds the lens with controlled pressure. No screws. No fragile clips. A system that holds when it should and releases when you want it to.

The nose pad bends by hand to match the shape of your face. Once adjusted, it retains its shape and keeps the frame securely in place, at rest and in motion. Hydrophilic silicone increases grip as your skin becomes damp, preventing slipping during activity.

The PHASE™ photochromic lens automatically adjusts to ambient light, darkening in strong sun and clearing as the light fades, with a smooth, continuous transition.
The photochromic molecules are built directly into the lens material instead of applied as a surface coating. This means they do not wear away over time and react uniformly across the entire surface.
The result is one lens that covers conditions from overcast skies to full sun, without needing a lens change along the way.

The SPEKTRA™ lens forms the base, with selective filtering built into the material to enhance terrain contrast. Three surface coatings are added: an anti-reflective layer on the inner surface, a hydrophobic and oleophobic treatment on both sides, and a scratch-resistant layer on the outer surface. Built-in impact resistance completes the structure.
WHAT DEFINES US
How does a photochromic lens work?
The PHASE™ lens contains photoreactive molecules built directly into the polycarbonate. These molecules change structure in the presence of UV rays and darken. As UV exposure decreases, they return to their original form and the lens becomes clear again.
A responsive, automatic system. No battery or switch.
How long does adaptation take?
The transition to a darker tint takes about 30 seconds once exposed to UV rays. The return to a clear tint is more gradual, taking about two to three minutes depending on the ambient temperature. In cold weather, the lens darkens faster and stays dark longer.
In use, the transition is continuous. You do not notice a sudden change between the two states while moving.
What makes SPEK different?
SPEK builds around what really matters to athletes. No overcomplicated designs, gadgets or futuristic promises. Comfort, clear vision, no fog and style that reflects current trends. The fundamentals, delivered without compromise. That's SPEK.
How do your lenses compare with the best on the market?
SPEK works with manufacturers that produce some of the best lenses in the sports industry. UV400 protection, SPEKTRA™ contrast and PHASE™ photochromic technology, and performance-level optics. Access to quality should not be a luxury.
Which sports are they designed for?
SPEK was developed around road cycling and running. These disciplines guided development and field testing. Meeting the demands of cyclists and runners means covering the essentials: stability in motion, ventilation, light weight and clear vision at speed. Those same fundamentals work just as well for trail running, gravel riding, hiking and cross-training. Designed for performance, ready for any terrain.
Les lunettes Stryve II sont très belles et confortables. J'ai un petit visage et elles me vont très bien.
Ces lunettes sont très confortable, légère et à un coût raisonnable. Très satisfait.
Super lunettes !J'ai demandé des lunettes de ski à la Mère Noël !
Vraiment incroyables! La vision avec les verres Spektra+ est malade, et que dire du design… 🔥 Look good, feel good, run good.

Best in Québec
Glasses are for biking and cross country skiing, fit great, comfortable and cut uv rays. They look pretty good too.
I ride my bike to work, so need a lightweight and reliable solution. The Kovo works perfectly -- the crystal clear lenses keep me safe and aware and they are perfectly visible during my darker mornings and brighter afternoons home. Great sunglasses and always happy to buy Canadian. Very satisfied and will buy again!
