Expert Reviews


What reviewers liked

Very well-crafted armband to go with. The newer smartphones have quite a big frame of 6” to 6.5” and this armband is designed keeping those phones in mind. A very interesting aspect of this armband is that you can even put the phones in their cases and still put them in this armband comfortably.
