Description
The Wiley X Alpine in the ACALP09 configuration is a wraparound with serious range and outdoor credentials. It runs CAPTIVATE polarized Blue Mirror lenses set in a gloss Crystal Grey Triloid nylon frame, and the whole thing is built to shrug off the kind of abuse a shop pair of sunglasses would never survive. The lenses carry a light transmission around 11 percent, which makes this a pair you reach for when the sun is high and glare is coming off water, snow, or a bright bay.
What the Alpine Captivate Lenses Actually Do
CAPTIVATE is Wiley X's contrast-tuning lens tech, and it filters the light spectrum to sharpen color separation and detail. On the range that means picking your target out cleaner against the backstop, and out fishing it helps you read water and spot fish. The polarized Blue Mirror tint knocks down harsh reflected glare, and you still get 100 percent UVA and UVB protection plus blue light filtering. The lenses wear a T-Shell scratch-resistant coating along with anti-reflective and oleophobic treatments to keep smudges and scratches at bay.
Fit and Durability of the Wiley X Alpine
This is a Medium to Large frame with a high-wrap, base curve 8 profile, so it sits close and blocks wind and debris from sneaking in at the edges. Rubberized nose pads and temple tips keep it locked to your face when you're moving, and folks who own several Wiley X pairs consistently call the Alpine one of the most comfortable in the lineup. Venturi Suction venting moves air across the lenses to fight fogging during hard use like cycling, running, or working a stage.
Protection You Can Count On
The Alpine meets ANSI Z87.1 safety standards, ISO 12312-1 for sunglasses, and the MIL-PRF-32432A ballistic impact rating, so this is genuine protective eyewear and not just a fashion tint. If you wear corrective lenses, the frame is RX ready and works with an optional prescription insert. Frame specs come in at 144 mm frame width, 127 mm temple length, 64 mm lens width, and a 15 mm bridge.

Frequently Asked Questions
Are the Wiley X Alpine Captivate glasses ballistic rated?
Yes. The Alpine meets the MIL-PRF-32432A ballistic impact standard along with ANSI Z87.1 and ISO 12312-1. That makes them true protective eyewear for the range and not just a tinted sunglass, so they hold up to impacts a standard pair would not.
What conditions are the blue mirror polarized lenses best for?
The Blue Mirror lenses run about 11 percent light transmission, which puts them in the bright, high-sun category. The polarization cuts glare bouncing off water, snow, and pavement, while the CAPTIVATE tech boosts contrast to help you pick out detail. They shine on sunny range days and open water.
Do the Wiley X Alpine sunglasses fog up during activity?
They are built to resist it. The Alpine uses Venturi Suction venting that moves air across the lenses to keep them clear during hard activity like cycling, running, or working a stage. Owners regularly note the anti-fog performance holds up well.
Can I get the Alpine Captivate in my prescription?
Yes. This frame is RX ready and accepts an optional prescription insert, so you can dial in corrective lenses without giving up the ballistic protection. Wiley X is known for a straightforward prescription process on their protective eyewear.
