DOUBLE-LAYER DESIGN: The top of the umbrella cap can be closed to seal off wind and rain, and is ventilated when opened.
EASY USE: Pull the string to open it. When you press and hold the button, it will automatically retract.
ADJUSTABLE HEADBAND: More stable and comfortable to wear. Fits most adults.
COMPACT SIZE: When the umbrella cap is closed, it takes up little space and is very convenient to carry.
