Those who partake in athletic endeavors that utilize a smartphone will find the design of the Twelve South 'ActionSleeve' Apple Watch armband to be quite useful. Compatible with the Apple Watch Series 1 and 2, the Twelve South 'ActionSleeve' works by allowing the device to be shifted in position from the wrist, to the upper arm. This keeps it out of the way during athletic endeavors without having to feel any sort of restriction.
The Twelve South 'ActionSleeve' Apple Watch armband creates a more precise contact with the skin to make heart rate tracking more accurate. The armband also works to provide protection for the smartwatch to ensure that hitting it with equipment won't render it broken.
