- Three adjustable heat settings
- Soft stretch fabric: 95% cotton and 5% spandex
- USB 5V/2.4A power connection; power bank not included
- Ideal beneath ski clothing, workwear and everyday winter layers
Choose your layer
Choose a 16-zone top or 12-zone trousers, then select the available fit, colour and size. Each piece can be worn on its own or paired with another thermal layer.
Fit guidance
This close-fitting base layer runs small. Choose one UK/EU size above your usual size. If you are at the top of a height or weight range, or prefer less compression, choose two sizes above your usual size.
