Reviewing sunglasses is tricky business. Its really hard to quantify things like clear, sharp, or defined. But those adjectives tend to roll off the page, describing good optics without much support.

　　Historically, a handful of top sunglasses brands have earned those accolades consistently. Although Wiley X is good, it hasnt been one of them.

　　Until now. Ive worn the Wiley X WX Founder model for 6 months. And more than once, Ive mistaken it for a pair from Costa, which Ive found consistently to make the best sunglasses on the market.

　　From the best my eyes can tell, Wiley X has leveled up.

　　In short: The Wiley X Founder is a medium-to-large sunglass with excellent comfort and remarkable lenses that compete with the best polycarbonate lenses on the market. Theyve proven relatively durable after 6 months of testing.

　　The author testing the Wiley X Founder while driving an ATV on a very dusty trail in Arizona; (photo/Sean McCoy) To put this out there as a benchmark, I personally think Costa del Mar is the current standard-bearer for quality sunglasses. But to get the best of Costa, you need to go with its glass lenses, which have two downsides: weight and a lack of protection.

　　This is where polycarbonate shines. Wiley X has brought a top-shelf polycarbonate offering with its Captivate lenses. Ive put the Wiley X Founder sunglasses with polarized green mirror lenses into regular rotation in the Colorado sun since January.

　　I used them skiing, hiking, trail running, and turkey hunting. They even came to Arizona, where I wore them on a dusty ATV ride and whitewater rafting. Just last weekend, I took them SUPing at the Chatfield reservoir near Denver, where they took a few unplanned swims with me while I was trying to teach my dog to SUP.

　　And darn if these sunglasses havent performed flawlessly. Theyre comfortable, easy on the nose and ears, and secure enough to not fall off during a few swims — even when my hat popped off my head from the impact with the water.

　　The lenses are also excellent. Do they compete with glass? Not quite. However, polycarbonate lenses that meet ANSI Z87.1 safety standards are about as good as they get.

　　There is one downside: They dont come with a hard case. Ive simply used cases from other sunglasses that I own. But if you need a hard case and dont own one, keep this in mind when shopping.

　　Who Should Buy the Wiley X Founder Sunglasses? Wiley X makes sunglasses with protection in mind. Founded in 1987 by U.S. Army veteran Myles Freeman Sr., the brands mission has been to “Build the world’s best protective eyewear.” That means eschewing glass for other, more protective materials.

　　These sunglasses are for those who want reliable eye protection that competes with the best optics on the market. At around $200, the Wiley X Founder also packs a premier price, which means its going against the best. And fortunately, it measures up.

　　Try on a pair. If they fit your face and you like the style, the Founder is an excellent pair of sunglasses that should meet the demands of most outdoor adventures.
