Fabulous. Have been buying these for years. Great that they now have a crew neck option. Really nice shade of grey. I am a size 10 but always buy a 12.

Thermal crew.

Nice fabric but quite a boxy shape… needs to be longer (especially in the arms).

Lovely!

Yes, I recommend this

Lovely feel to this top and it’s really cosy. We haven’t had any really low temperatures yet this winter but it certainly keeps me warm especially when I’m out walking the dogs.

Love these Heatgen tops

I have bought this in all the colours. They are practical and warm and cosy to wear under jumpers, cardigans and dresses in the winter months.

Great quality

Yes, I recommend this

This top is somewhat thicker than most in the range, but will be just what you need once the colder weather arrivals they have a warm fleecy interior and will be ideal when out dog walking in the winter. Only downside was the sleeves were to long, I shortened them so more comfortable to wear.
