SPY Screw Under ReviewMay 20, 2015
- Lightweight design with durable Grilamid® material
- Wide field of vision
- Polarized Happy Lenses™ that enhance color and contrast
- Interchangeable lens system
- Solid styling
- Nosepads are not adjustable for a custom fit
- Frame material is slightly stiff
Spy has brought style and performance to the outdoor arena with the Screw Under—a truly standout feature of this sunglass. The Screw Under, which is designed in lightweight Grilamid, was a strong contender in this sunglass test. This smaller-profile sunglass delivers a full visual field while at the same time, not overwhelming the face. I’m also a fan of SPY’s Happy Lens™, which offers solid visual clarity, definition, and color contrast enhancement. My gripes: I’d love to see adjustable nosepads on this sunglass for a more custom fit, and while Grilamid is lightweight and durable, it can also feel slightly stiffer on the face than some other frame materials.
Fit & Comfort
The Screw Under slides on (and stays on) comfortably. The smaller lens size is spot on for medium to small faces. This sunglass also has Hytrel rubber nosepads that delivered excellent grip, even when running or mountain biking over technical terrain. The 7-base wrap—that’s a pretty curved wrap, as far as wrapped lenses go—also delivered excellent protection from the elements, from wind and bugs to flying road debris.
I tested the Screw Under with SPY’s Bronze Happy Lens with Blue Mirror, which was a great option for sunny, glare-inducing conditions. According to the company, SPY’s Happy Lens cuts out the sun’s “bad” rays and lets in more “good” rays, inducing a “happier state”. And in testing, I actually felt pretty happy wearing these shades. The Happy Lens definitely offers noticeable optical clarity, glare reduction, and visual definition that’s critical on the trail.
I tested the Screw Under during icy winter blasts and windy spring conditions and found that its fully wrapped design worked well to cut the blast, although slightly less effective than other larger lens sunglasses tested. This sunglass also has a ventilation system that cut down fogging during my aerobic activities.
