Winter warmer

Yes, I recommend this

Great thermal tops. The scoop neck means that they are not visible underneath other clothes. Great for layering and definitely keep me warm.

Great product

I like the comfort of the product. It feels soft on the skin and covers very well the bottom of the back.

Thermal Long Sleeve Tops

No, I don't recommend this

These are very thin. I bought two thermal tops a couple of years ago and they were much thicker. I've obviously slipped up as I thought I remembered them being more expensive last time. I had already opened the pack and thought they will have to do. Nothing wrong with them, just wasn't what I was expecting - my error.

So very cosy !!

Yes, I recommend this

I bought these last year, i was so pleased with them i bought them again this year, even though last years ones are still very wearable. So thin you can layer up, yet so very warm.

Thin but nice

These are quite thin. They are warm but more of a vest than a top. I am wearing them when it’s not too cold.

Great quality

Yes, I recommend this

These tops are not only practical but go with virtually everything. They are super warm and comfortable to wear. I find myself wanting to put them on underneath all my tops and blouses for extra warmth. Not sure if they came in other colours but if not, it would be nice if they did.

Winter warmth sorted

Yes, I recommend this

Same quality but boring compared to my pretty ones purchased in years gone by. Lace effect - animal prints - sparkly etc. these are dull in comparison.

Excellent Quality Lightweight Thermals

Yes, I recommend this

I bought these in order to have a variation of Heatgen thermals this winter, from lightweight through to Arctic thermals. I particularly like the dark grape colour but wish they came with a crew neck rather than the scoop. Also, can we have a medium thermal in dark grape with a crew neck please? I had previously tried my usual size of 14 in store but found it too skin tight for my taste. So I was confident in ordering the size 16 online, which is perfect.

Do the job

It's a 'dirty' cream, previous ones were a nicer colour.
