Love these thermal tops. Can be worn on their own or under clothing in cold weather. Fit like a second skin and keep me so warm. Good quality, lovely and soft, quite a range of colours.

Another winter.. a few new heatgems … perfect solution to keep warm whether it’s worn under a dress or paired with a cardigan, it’s neat and cosy and comes in several styles and lovely colours..They wash well and keep their colour.

Not high neck

No, I don't recommend this

I returned this as not a high neck but turtle neck and quite faded looking black. I'll wear my own roll neck jumpers with a thermal vest underneath

loved the berry colour, I didn't realise that the fabric was more like a woolly jumper much to thick for layering that I required so had to return
