Hello, good evening, I wanted to tell you that this month of July I bought 2 pairs of the gray model and previously a pair of that same model that you present, and all 3 have a big defect, perhaps for this climate in Miami, that they are not breathable, and they appear sweat stains on the top and sides, I have photos of them, the 3 models are from Vietnam. purchased on their main page. It's a shame because they are still one of the best designs. thank you so much
