Why doesn't the fan turn on?
Check to make sure that the vest-to-fan cable is securely connected. Be sure to press and hold the controller button for 3 seconds to power on or off. Press once to cycle between the fan speed settings. Note: some third-party batteries may require you to press a button on the battery to activate power. If necessary, please power on your battery and attempt instructions again.

The fan is working, but doesn't seem to be effective?
Check to make sure that the dome-side of the fan (the side with arrows) is facing inward toward the body.

Can I wear a jacket over my vest?
We do not recommend wearing any garment that can obstruct the fan's ventilation. For optimal cooling performance, wear the vest over a simple base layer or shirt.

Can I use my vest when it's raining?
We do not recommend wearing your vest in excessive water exposure conditions.

Can I wash my vest?
Yes, please completely remove the fan and battery from your vest before washing. Use mild soap and water, and hang or lay flat to dry.
