Tifosi Jet Interchangeable Sport Sunglasses for Cycling, Running & Outdoor Activities - UV Protection & Lightweight Design

This is my second pair of Tofosi glasses. After nearly 8 years of switching from dark lens to clear lens when I ride my mountain bike, the dark lens finally cracked at the nose bridge. Since I change lens fairly frequently I looked for glasses that offered this feature. I succumbed to my tite-wad gene and bought a cheap set and they don't fit worth a darn-ride too high on bridge of my nose. These Tofosi glasses fit nicely.Not sure if I got lucky, but these glasses stay on quite snug on me, although when a friend tries to use them, they fall off when they shake their head. Material seems a little weak, but that might be on purpose to make it light weight. Completely recommend getting a head band with these! Last thing, changing the lenses is very anxiety inducing, so I do not recommend it, just leave the ones that are on already and enjoy!I like the glasses but they lens inserts are so tight I fear it will break if I try to change them.Great for price and does include 3x pair of lens!Fit my small head
