HeatIQ warmth levels

When it comes to thermals, we know it isn’t a ‘one warmth fits all’ approach, which is why our HeatIQ range is available in three different warmth levels: Warm, Extra Warm and Max Warm. Find the right style to suit you and your needs below.

Warm:

Identifiable by their yellow icons and font, these are our entry-level thermals. Made with a viscose-rich pointelle and ribbed fabrics, these are designed to act as heat-retaining base layers to keep you warm. Selected kidswear styles are made with cotton instead of viscose.

Extra Warm:

Distinguished by orange icons and font, these are our mid-level thermals. Featuring a softly brushed fleece made with THERMOLITE® EcoMade technology, these strike the perfect balance between a light base layer and a heavy-duty option. 

Max Warm:

Looking for maximum warmth? Look for the red icon and font. Designed with a cosy, velvet plush inner layer, these provide our highest level of heat retention.
