Great for a man!

Yes, I recommend this

I bought this for myself but it is actually for a man. Not sure whether I was confused or the website is misleading. Anyway my husband likes it and it’ll be perfect for skiing.

What I wanted was great quality.

As I was paying £25 for it - I assumed that there were 3 vests inside, as mosts vests are in packs of three. To my surprise, there was only one (my carelessness of course), so this will be returned to the shop. What I was after was the packet of three vests - top quality cotton - stock no.07486821 3 part set. Large - chest 41- 43 ins. T14 5820D/00385 White (L) When I go back to M&S for the refund, perhaps I can buy what I wanted. When I return to M&S

Mistake

Yes, I recommend this

Made a mistake - thought this was for a woman but it’s very obviously not! Having said that it’s warm and as it’s long it keeps my bum warm too!

Warm and comfortable

Yes, I recommend this

I bought these for my husband who really feels the cold. I was interested to see that, unlike most thermals, they also contain merino wool. The fit and quality is excellent and my husband now feels warm and comfortable. They wash well too!

Doesn't live up to its name.

No, I don't recommend this

I bought the maximum thermal top because I thought it would keep me really warm, but it is no better than the much cheaper thermal tops M&S sell. Not good value at £25.

Great quality, feels nice, good length

Yes, I recommend this

Nice, thick material which is soft and fleecy on the inside. Nice and long in the body so easily tucked in and doesn’t creep out of trousers as you move about! The black looks like a normal t-shirt , retains its colour and shaping on washing. Has kept me nice and warm in my early shift starts and working outside.

A classic winter thermal top

In cold weather a winter thermal top is ideal. This top is comfortable and gives good insulation.
