Style and Functionality for MTB
- Familiarity: I've put it through the wringer
- Fit: True to size
I primarily use these glasses for mountain biking and I'm pretty stoked on them. I chose this specific model because I'm not a huge fan of how I look in those classic cycling-style glasses. These are much more casual and styley, but also pretty functional too!
The fit: Really lightweight frame, the arms do not pinch or squeeze my temples, nor do they slip or jostle around while biking down hill! The lenses are on the larger side, but don't stick out. In fact, they hug your face quite well without looking like they're suctioned onto there and with just enough space for good ventilation.
The visibility: These are my first photochromatic lenses and I'm a fan! Do they change instantly? No. If you're on a bike you won't notice them changing as the trail ducks in and out of the trees. But do they always seem to have the best tint for the day's conditions? You bet! I was nervous that the yellow lens would be a bit much, but the VLT range (Visible Light Transmission) that these transition to, combined with the polarized lenses, never seem to leave me squinting or straining my eyes. Very impressed.
The construction: So far, so good! As mentioned above, the frame seems super light and I never really feel aware that they're on my face. But, the arms and frame seem thick enough to make them fairly rigid, although I haven't quite been willing to test that yet. The rubber on the temples and nose bridge is soft and non-intrusive and seems to do the job. Had them for a few weeks and the lenses seem to be scratch free, which somehow I usually manage to scuff up.
Downsides: Not much really. Occasionally after a long uphill pedal and a lot of sweating, they'll begin to fog when I stop for a breather. But that usually takes care of itself the second I get airflow movement again.
Bottom Line: Despite the yellow lenses, these shades perform great in the sunniest of days and obviously the shady ones too. As a mountain biker, they help highlight all those little roots and ruts in the shadows of the trail that might otherwise be hidden to me with a darker pair of glasses.
