The Sporteer Entropy Running Armband is designed to fit the Galaxy S20 Plus with no case or thin* cases.
Entropy armbands feature removable armband straps and soft memory foam backing to provide a comfortable, water-resistant, sweat-proof and secure fit on any arm and ensures your S20+ won't 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 S20 Plus and other small personal items while running, cycling, hiking, weight training, and traveling.
*The Entropy Armband for Galaxy S20+ fits cases up to 165mm X 90mm.
