Over the years I have tried a few different armbands. Usually, these are the type with a clear cover completely encompassing my phone. Since I sweat, a lot, my phone would almost certainly get wet. Sweat was never really much of a problem. However, I would use a GPS app on my phone and eventually I would get erratic tracking making my phone useless. As a result, I stopped using my phone to track my fitness activities and bought a GPS watch. After a year, I was less than impressed with the watch and slowly returned to using my phone app.
I spent an evening looking for the perfect armband when I came across the Tune Band. After reading countless reviews I decided to buy one. It came with two armbands, one for smaller arms and the other for larger. I chose to go with the glow-in-the-dark cover. It holds my phone securely with now worry of the phone falling out. The face of the is not covered and I have not had any problems with the GPS. I recommend this armband to anyone who runs with their phone.
