Sporteer Entropy Running Armbands are designed to fit smartphones with protective cases - and who has the patience to remove a case before every workout?
Sporteer Entropy Armbands are offered in two pocket sizes to ensure a comfortable and secure fit a wide range of phones 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 phone 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.
