Verified Purchase(What is this?)
This review is from: VeloChampion Tornado Sunglasses Black with 3 Sets of Interchangeable Lenses and Soft Carry Pouch (Sports)
These are inexpensive and do exactly what they need to do. Having the different lenses to swap out is very useful, though I tend to stay with yellow as they help to pick out detail in the terrain and also give the impression that the weather is better than it really is, which is nice.
