Lovely quality material.

Yes, I recommend this

Nice soft material and adds a warm base layer. Unfortunately this was too long in the body so awkward to tuck in to jeans etc which is why I knocked a star off.

Good quality

A good thermal weight for a shirt sleeve vest, glad I was getting 20% otherwise a but expensive. My husband usually buys XL but M&S vests come up abit narrower so buy 2XL

Works a treat!

Yes, I recommend this

This was a further purchase of one of these vests. I bought one last year and found it exceptional in the cold weather. At the same time as keeping me warm, it also seems to be able to regulate body temperature so you don’t overheat.

So soft and warm!

Yes, I recommend this

I bought this for my husband. I'd bought the women's brushed cotton vests for myself and found them so soft and warm that I wanted him to experience it too. Needless to say, he's hardly taken it off!
