Namesake Trail

Mineral King

The Mineral King Loop is 36.3 miles with 12,140 ft of breathtaking (literally and figuratively) vertical gain taking you through subalpine valleys and high granite peaks. A quirky aspect to watch out for with this trail is the marmots known for wreaking havoc on campsites and even cars in the area. Read more about the pesky marmots here. 


Drew Antonisse currently holds the only known time at the moment at 9h23m5s.

Performance

Trail Ready

The adjustable temples allow you to create the perfect fit. Combine the adjustable temples with the no-slip-grip nose piece and you can hit your hardest efforts without worrying about your glasses falling off your face. 

Materials

Trail Tough

Lightweight, flexible, and extremely durable. Our premium frames are constructed of a recycled nylon blend that gives you the performance and durability you need at a lower cost to our environment.

Optics

Trail Vision

FKT’s shatter-proof polycarbonate lenses aren’t polarized because polarization isn’t what a trail athlete needs. Polarization is wonderful if you’re on the water or snow, but it can cause depth perception issues if you’re running on a trail with variable light conditions. That’s why we opt for our Trail Vision tech which provides 100% UVA/UVB protection. All lenses are treated with hydro-oleophobic, anti-scratch, and anti-reflective coatings to ensure you maintain a consistent field of view through ever-changing conditions.

Extras

Trail Goodies

Protect and clean your glasses with environmentally friendly accessories. All FKT sunglasses come accompanied by a protective case, recycled microfiber pouch, and recycled microfiber cleaning cloth.

Killer glasses for running/golfing/fishing

I’ve had these for about a month and been loving them. Mainly been using them for running, but also been great for golf and fishing. Fit is super comfortable, don’t fog up at all, and the color and darkness of the lenses is perfect for taking out the glare but not being too dark. Highly recommend.

Best hiking and driving sunglasses

Have had these now about one month.
I have never been able to be very compliant with eye protection in the past because sunglasses squeeze my nose and pinch behind my ears and give me a headache.
These sunglasses fit so well and are the most comfortable I have ever found.
I will wear them hiking and don't realize I am still wearing them and garden and work in my yard all day and never have to take them off due to pain.
After being outside for 8 plus hours my eyes feel rested and comfortable and my ears are pain free.
I bought the peridot color

The best running glasses I've ever owned

Love everything about these. The adjustable sides, the nose piece, the style of them, and the size. These fit with a hat really well and you can wear them for runs or casual.
