Trail Ready

The adjustable temples allow you to mold your High Lonesomes to your liking. 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.


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.


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.


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.

Cute and comfortable

These sunglasses are stylish and can be used for any outdoor activity. I can take a run and also go out in them.
I love the comfortable nose piece and ear adjustments.
I have the white style and love them.

Lightweight and durable!

These are incredibly lightweight and make the perfect accessory for out and about or mountain biking. I have had no scratches thus far which is a surprise given all the dust and rocks that fly up while biking. The adjustable ear pieces are an added bonus for my small frame face and these are my only glasses I’ve had that don’t slide down my nose. Can’t go wrong with these!
