Common Questions About the Flexcore

What does 'dual control' mean on the FlexCore base layers?

Dual control lets you independently manage separate heat zones on each piece, each with its own low, medium, and high setting. On the shirt, control the front (chest) and back (neck and upper back) independently. On the pants, control the thigh and glute zones separately. You can customize your warmth based on where you need it most, or turn off zones to extend battery life.

Can the FlexCore base layers be worn on their own or only under other clothing?

Both. The FlexCore base layers work great under jackets, sweaters, or outerwear, but they're also comfortable and presentable enough to wear on their own in milder cold. The slim fit and clean design make them versatile for different situations.

How long do the batteries last with all zones running?

Each piece includes its own 10,000 mAh battery. The shirt provides up to 9 hours on low and the pants up to 8 hours on low, with shorter runtimes on medium and high settings. Running fewer zones at a time will extend battery life if you need all-day warmth.
