Lovely material

No, I don't recommend this

Lovely material, but so long. Because it is so long it ruffles up when wearing trousers, I’m 5”6 so I can’t imagine how someone not as tall coped. Also the straps are not adjustable. Shame because the inside is superb.

Great warm vest

Yes, I recommend this

The vest was really warm on the inside as mentioned & I found it so nice that I bought another in brown. I bought a bigger size than normal & it was longer in length

Very warm, perfect for spring weather

Yes, I recommend this

Ordered this in the pale colour. Despite being sleeveless it's very warm, so it's perfect under a blouse in spring. I was worried my arms would be cold, but the heat it retains keeps my whole upper body warm. It is a long garment, covering part of the butt, but I assume this is to better insulate your whole torso from the cold. It is thicker than an ordinary vest and very soft.

Warm Camisole any day Top

These vests are amazing. Throwing out all my cheap ones. Really adds extra warmth under any outfit. Looks great on its own. M&S can you make these in summer shades as we are all chilly even on UK summer days. I’m a 16 bought 14 (black/brown)

Best thermal vest ever!

Yes, I recommend this

Absolutely love this vest. So soft and very warm. Also very good value. I Would have given a 5star rating except for one thing. I am quite tall, but this vest is very long indeed. As I always wear trousers or jeans it comes down quite far and the thick bottom seam can be seen under the jeans.
