Heat Holders

Whether you need thermal protection outdoors or some extra warmth and comfort at home, this Mens Original Thermal Underwear Top in Black will make your life warmer.

Heat Holders men's thermal underwear features micro-fleece fabric, with ideal stretch properties and comfort seams to allow full freedom of movement and a comfortable, non-chafing fit that’s perfect for layering your base layers. Finally, moisture and odour management technology help to keep you warm dry and fresh all day long.

Our love of warmth and comfort is backed up by proven science and over 50 years of technical expertise. At the core of every Heat Holders base layer is our advanced super-soft thermal microfleece, combining performance insulation, comfort and dryness. But the real secret of our warmth lies inside: our expert brushing process creates a soft fur-like pile that holds even more warm air close to your skin, maximising thermal performance and comfort to keep you warmer for longer.

Heat Holders base layers are available in three different thicknesses.

  • Original is our thickest and heaviest base layer, perfect for extreme cold.
  • Lite is our medium thick base layer, ideal for very cold days.
  • Ultra Lite is our lightest base layer, great for everyday cold.

For optimal warmth and comfort, we recommend you consider both activity levels & temperature. Our thicker base layers may be better when activity levels are low, while our lighter base layers may be more appropriate when activity levels are high.

Please check the size guide above before purchase

It keeps me warm and is lightweight enough to wear under jumpers etc

Good, But

I found the Heat Holders thermal top the best I`ve ever tried with regards to warmth, I choose medium for size but found the top can up quite short and I`m only 5ft 6inches

Excellent value

My husband says they are the warmest vests he has had

Thick, warm and comfortable

If you're outside in the cold for any length of time this is an excellent base layer. A snug but not at all constricting fit, soft and thick but still sits nicely under outer layers. Keeps me warm working outside in minus temperatures.

warm and comfortable

Warm thermal top for winter. Durable too. Slightly thicker than usual. Fast delivery outside the UK. Would recommend
