Using your Fieldsheer Men's Heated Backcountry Jacket is easy. First, make sure the battery is fully charged. Then, press the waterproof touch control button to turn on the jacket. You can use the 4 selectable heat settings to adjust the temperature according to your needs. You can also connect your phone via Bluetooth and use the MW Connect™ Mobile App to control the heating. When you're not using the jacket, store it in the stow - away carry bag. Keep the jacket away from sharp objects to avoid tearing the outer shell. To clean it, follow the care instructions on the label. Generally, it's best to use a gentle cycle and mild detergent. Don't forget to remove the battery before washing.
