The E8 Armband is designed to fit large phones with or without protective cases and features removable armband straps and soft memory foam backing to provide a comfortable, sweat proof and secure fit on any arm.  The E8 includes two interchangeable straps sizes so it can be worn directly on the arm or over clothing, eliminating the need to have multiple armbands for changing weather conditions.

The E8 is the perfect way to carry your large smartphone and other small personal items while running, cycling, hiking, weight training, and traveling.

The Entropy E8 Armband fits all smartphones, protective cases & battery cases up to 165 x 90 x 16 mm.
