These vests are not the same as I have had before but they seem to be the same good quality.

Very warm, perfect for spring weather

Originally posted on marksandspencer.com (UK)

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

Originally posted on marksandspencer.com (UK)

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!

Originally posted on marksandspencer.com (UK)

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.

Lovely colour, warm vest top

Originally posted on marksandspencer.com (UK)

Lovely colour top. Warm to wear. I have kept it, however, I think it comes up bigger than size. I ordered a size 10 and quite easily fit in a size 8. I shall get another in a smaller size.

Cream Thermal Medium Warmth

Originally posted on marksandspencer.com (UK)

Hoping to replace a cream thermal vest with shoulder straps you can alter, I thought this was the one. The straps are not adjustable and as a Medium warmth are ‘brushed inside’ for extra warmth. My old one must have been lightweight but couldn’t find the equivalent online. Kept for next winter, only bought because of sparks offer making it reasonable value. Never sure of M&S sizing now, so always have to order at least two different sizes.
