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.

Great for layering

Yes, I recommend this

I love these soft tops. I layer them in really cold weather or just wear them under a lighter top when necessary. They are really comfortable to wear (even used them in bed!) and wash well.

Yes, I recommend this

Lovely and cosy. But can't be used as a t-shirt alternative as the neck finish is loose.

My mistake I ordered men's medium!

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

Yes, I recommend this

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?

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

Great layer

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.
