The Sporteer Entropy Running Armband is designed to fit the Galaxy S8 with protective cases - and who has the patience to remove a case before every workout?
The Sporteer Entropy Armband is offered in two pocket sizes to ensure a comfortable and secure fit for your S8 with no case, thin case, or even thick cases like Otterbox Defender.
Entropy armbands feature removable armband straps and soft memory foam backing to provide a comfortable, sweat proof and secure fit on any arm and ensures your S8 will never slip down your arm. Two interchangeable strap sizes are included so all Entropy armbands can be worn directly on the arm or over clothing, making Entropy the perfect armband for all seasons.
Entropy Armbands are the perfect way to carry your Galaxy S8 and other small personal items while running, cycling, hiking, weight training, and traveling.
