I purchased these glasses after Tifosi stopped making the Slip with the Light Night frame. I believe they have since resumed production of that combination.

Light Night starts out nearly clear and darkens as needed. I wear these glasses year-round including in the dark. This is one of the only color-change lenses on the market that gets this light.

The Tyrant frame is comfortable and mid-quality... what I would expect from Tifosi. My issue with the overall design is that the lenses are short and do not contour to your face. The end result is a sizable gap between the bottom of the lenses and your face. On a bike, this lets in more air than is desirable. While I will still use these glasses, I will replace them with something different next time.
