Heat Holders

Whether you need thermal protection outdoors or some extra warmth and comfort at home, these Ladies Original Thermal Underwear Bottoms in black will make your life warmer.

Heat Holders ladies 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

Bis heute habe ich die Unterhose nicht erhalten.
Wo ist die abgeblieben?

Feel like a teddy bear

Sizing is good. But movement in fabric is not as flexible as I’d like Was sent the extreme cold leggings & having trouble trying to exchange ?

Ladies Thermal Bottoms

I bought these for my partner as an Xmas present as she complains of cold legs at this time of year. According to her, although they are very warm, they have a tendency to ride up the leg leaving her ankles exposed to the cold. After washing them, they also shrank in length exposing even more of her legs to the cold! It won't put me off buying more Heat Holder products as they are the best when it comes to keeping warm but these bottoms aren't as practical as the 0.52 tog rated leggings/ tights (also available on this website) and cost more for some reason.
