Universally sized to fit phones and devices up to the size of iPhone 6s and Samsung Galaxy S7, the Nite Ize action arm band is a durable, flexible and sleek way to stay connected while you're hiking, running or in the gym. Just slide your device into the main pocket, thread the weather-resistant microfiber strap through the lightweight metal loop, press it closed around your upper arm and go. Because the main pocket is faced with clear, touch-responsive TPU, your phone stays visible and functional as well as protected. Other design features include: strategic openings at both top and bottom for headphone access, a rear slot to fit a driver's license, credit card or cash; micro hook-and-loop at both pocket flap and arm strap for secure, streamlined closure; and a smaller second slit pocket with attached S-Biner® (for a key) and CURVYMAN™ Cord Supervisor™ (for ear buds) included. Ventilated and non-absorbent, the microfiber construction of the Action Armband repels moisture, is lined with reflective detail and backed with two narrow gripper strips to prevent slipping. Sonic welding construction ensures a flatter, smoother fit, with no seams or stitch lines to chafe or irritate your arm.
