Great shape & cosy

I don’t wear this for as undergarment but as a really cosy top with my jeans/trousers and also under my ‘walking jacket’! Great value too!

Lovely warm and useful tops

Yes, I recommend this

I have these tops in many colours. I wear them most days with trousers and pinafores. They look particularly nice paired with trousers of the same colour. They are warm and wash extremely well. Every time i see a new colour i buy it. I i have tried different necklines but my favourite is the crew neck.

So comfortable

Yes, I recommend this

Material is nice and stretchy and did the job of keeping me warm. I will say it did bobble after the first wear but this is more of a layering piece for me so not a major problem. Also because I got the cream it was a little bit see through but if you have a nude bra it wouldn’t be seen.

Good Thermal top if a little long

Yes, I recommend this

The thermal tops are really good value for money but I do find most of them really very long in the body which only increases when you wash them, however they are stylish and warm.

Heatgen medium thermal vest

Yes, I recommend this

This is one of three I have purchased I like the fit they are warm and comfy. I wear them under a gillet and older ones I now use as pyjamas with the matching leggings keeps me cosy. They wash well and I usually buy a size larger as I like a loose fit. I love the different colours available too.

Great every day cosy T-shirt

Yes, I recommend this

I normally buy the scoop neck however they don’t seem to make them anymore. This was perfect though and will definitely buy more. I always size up a couple of sizes as they’re really tight otherwise.
