Excellent quality

Yes, I recommend this

Nice material, wash up really well. Several colours to choose from. Great to wear under a long sleeve casual shirt and stay warm without a jacket.

OK but not great

No, I don't recommend this

Is OK but nowhere near as warm as I'd hoped. Also pretty big round the neck which doesn't help. Will keep looking for a warmer base layer.

Xmas gift

Bought as Xmas gift so can’t review on size etc. Materials feel soft and expected to be good quality as M&S normally is 🤞

Comfortable & Cosy

Yes, I recommend this

I bought the vests to be worn under shirts in the winter. They are very light and warm, however as the neckline is so high it shows under my shirt which I really don’t like.

Great value and lovely and soft

No, I don't recommend this

Good fit and very soft to wear. Does not look like a thermal T shirt so can wear as a T shirt as well
