This is my second pair of Native Throttle sunglasses. I purchased my first pair about 8 years ago and have never been happier with another pair of sunglasses ever since. these really are the best! I run in them and they feel weightless. These are great for people with slender face and very little nose bridge.
Every two years or so, you do need to change out the lenses - the coating of the polarized lens cracks, causing a very thin clear line across the middle of the lens. You can purchase replacement lenses with any Native retailer.
One of the best things about these glasses are the "vents" that help prevent fogging.
I purchased this second pair because my first pair was stolen. This newer pair of Native Throttle is slightly lighter than the previous pair that I owned... definitely very nice... however, and this is my only disappointment, the quality of the workmanship is not as good as my first pair.
Native Throttle is still the best!
