## Description

Designed and thoroughly tested in the USA by athletes, for athletes, the Sporteer Entropy E6 iPhone X Armband is engineered to fit the iPhone X with no case or with a case. THE ENTROPY E6 ARMBAND FITS ALL CASES UP TO 152 x 80 x 16 mm. IF YOUR CASE IS LARGER THAN 152 x 80 mm, WE RECOMMEND THE SPORTEER ENTROPY E8 ARMBAND - SOLD SEPARATELY. The soft, moisture-wicking memory foam backing ensures this armband stays in place while running and protects your phone and other items from sweat and moisture and features modular/removable straps to ensure a perfect, comfortable and secure fit directly on skin or over clothing. Do you want to wear your armband directly on your arm in warm weather and over clothing in cold weather? Now there is no need to buy two armbands - just pick up a different strap size at a fraction of the cost and have a perfect fit no matter what your wear. TWO STRAP SIZES INCLUDED: S/M Bundle: Includes one Small Strap and One Medium Strap M/L Bundle: Includes one Medium Strap and One Large Strap Strap Size Arm Size (upper arm circumference) Small 8 - 11 inches (20 - 28 cm) Medium 10 - 14 inches (25 - 36 cm) Large 13 - 18 inches (33 - 46 cm).
