About this style

These long-sleeved thermal vests use our clever Heatgen™ technology: an innovative fibre blend, helping your body to generate and retain heat so you can stay warm when the weather gets chilly. Regular fit with Flexifit™ 360 degree stretch, so your vest moves with you and holds its shape. Heat-sealed labels and super soft seams that feel gentle against your skin. Moisture-wicking fabric keeps you dry and comfortable.

Light warmth for cooler conditions and everyday comfort.

My mistake I ordered men's medium!

Originally posted on marksandspencer.com (UK)

Quite fine material (men's medium in size). I am female and chose the men's (by mistake) but they fit albeit long. I would say I prefer a thicker base layer - less baggy looking.

Nice Quality

Nice quality. Wanted the burgundy but out of stock. Have bought these for years and like them a lot as basic day in day out base layer. My only criticism is why no white version (who wants ivory??). otherwise great and recommend

Good quality but why cream?

Originally posted on marksandspencer.com (UK)

Good product except why are they cream? All your other vest and thermal options offer white but not in the Heatgen Light???

Great layer

Originally posted on marksandspencer.com (UK)

Hubby loves them. They are thin but warm and also very long in the body so they stay tucked in. Lovely and soft to wear. Good blue colour. Highly recommend.

Warmth and comfort

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I usually go with Uniqlo on the basis that they have nailed the next-to-skin comfort, so was a bit sceptical when I ordered these. Thankfully, I can report that these are almost identical and deliver on the promise of warmth and comfort without doubt.

I bought a pack of these for my husband at Christmas. He feels the cold these days, and liked them so much I got him another pack. They fit him well and are very comfortable and do wash well

Brilliant top. Nice and light so you don't feel like you're wearing a huge underlayer but definitely keeps you warm in the colder months!
