I have purchased many products from this company, and they have all be great! No cheap stuff here!
Great arm band, one of the best I had found for the price. While it does resist sweat for most of the day, I had found that after some longer runs, the bottom part of the phone had moisture on it from sweat, although the top did not. Great product overall, if the sweat did not penetrate it would be 5 for sure, but overall the best value in armbands!!!
