New Universal Auto Adjustable Sport Armband Black

The band uses flexible silicone material, so it is stretchable and compatible with 4.7-6.0 inch smartphones. Carry your smartphone in style while playing sports.

The outside of the belt is made of PVC material. The waterproof feature means that your belt will not get wet. It can be used widely by both men and women by simply turning the dial.

The dial can be adjusted steplessly so you can adjust the position and tightness to your preferred length. The interior is made of a material that feels good to the touch, and it is breathable and wicks away heat to prevent stickiness caused by sweat.
The smartphone holder can rotate 360 degrees in a flat surface and adjust it every 90 degrees, so you can operate your smartphone at a comfortable angle.

It is sure to be useful for running, climbing, cycling, and other sports activities.
It will hold your smartphone firmly even when you run with your arms, so you don't have to worry about it falling off. You can use it for a variety of uses such as jogging while listening to music, or managing your health with the smartphone app.
