Customer comments

I wear HEATTECH Extra Warm when I go to watch sports games. In a crew neck, my neck gets a bit cold when it’s windy. It’s too much bother to wear a scarf.

(Male, 30s)

The latest addition to our popular cotton-lined HEATTECH Extra Warm range is the HEATTECH Cotton Mock Neck T-Shirt. As well as providing extra warmth, the on-trend mock neck looks great layered under a sweater or hoodie.

I can tell the difference from the previous version. It’s lighter, softer and stretchier. Above all, I love how warm it is. I wear it as a single layer like a regular T-shirt. It’s a shame it’s only available in a limited choice of colors.

Please bring these back. I love wearing AIRism Steteco Shorts in summer and HEATTECH Steteco Shorts in winter. But when I went to buy HEATTECH Steteco Shorts, they were no longer available. I will have to wear AIRism Steteco Shorts this winter.
