"The Mountain Lab app is used to control Mountain Lab Gear heated garments with Bluetooth® control. 

Mountain Lab heated garments can easily be paired with your smartphone device for a seamless experience.

The app allows the user to adjust heat settings, place garments into standby mode, set a timer, turn off the devices and monitor battery life, all from within the app.
Garments can be renamed, grouped (for paired items, such as socks), ungrouped or removed.

The Mountain Lab Gear app features a choice of English and French language settings."
