Perfect for layering and great quality

Yes, I recommend this

The quality of these vests is great. They are lightweight and soft, wash well and keep their shape after wear and washing. A great layer under almost anything.

Everyday base layer

Yes, I recommend this

Sometimes wearing a jumper indoors is too much but wearing one of these under a shirt is just right for cosy winter comfort. Easy to wash and tumble dry

Disappointing

No, I don't recommend this

The main reason I bought these was for warmth and for the nice low neckline meaning it can’t be seen under a shirt. However I have been disappointed and have found these to be very flimsy and difficult to wear. I always spend a good few minutes trying to rearrange the material to an acceptable shape before I can put my shirt on. They are warm as expected and the range of colours is good. However I won’t be purchasing these again.

Invaluable!

I bought these tops previously as thermals for skiing. But I use them all year round over gym kit as a warm up layer and under jumpers and shirts/ blouses.They are invaluable?

A comfortable Base Layer

Blue colour is lovely. Although not clingy this is a neat fit even going up a size. It’s purpose of warmth is good but could not wear it unless it’s under another layer.
