These armbands are lightweight, sweat proof and aerodynamic. They will protect your phone, keyFOB, credit card, cash or other items while training or racing. The design is new and innovative. The armband allows users to zip open that armband so that it is totally flat. This feature enables fast, easy access to Smartphones, credit card, cash, or KeyFOB/key. Other armbands force tricky and unwieldy motions to remove such items. This armband fits mid-sized Smartphones such as: iPhone X/8/7 with slim protective case, Samsung S9/S8/S7 with slim cases and other similar Smartphones. The touch screen is superfast and accurate so that users can access their Smartphone screen instantaneously without having to remove their phone. This armband also is the first in the world to incorporate a finger print sensor we call HomeTouch™. Users have their choice of using either Bluetooth or corded earphones with the armband. The appropriate slots for all types of Smartphones are included on the bottom of the armband.
