Simple warm vest

Perfect vest top to go under clothes. It’s very soft and definitely keeps you warm. Probably can just use as a vest top

I absolutely love these vests as I always feel the cold I wear one most days of the year. They wash really well and dry so quickly. I’d hate to be without them

Thin warm vest.

Love how thin it is and it does help when you’re cold. Ideal when you’re going to the shops just to keep you warm enough.

Just what I wanted!

Usually buy something extremely similar from a well known thermal underwear firm and these are just as good and better value as a 2 pack! Very pleased!

Lightweight and versatile

Lightweight yet brings an extra layer of warmth when needed. Discreet under clothing. Washes and dries easily.

Warm vests which can be worn under clothing in the winter for warmth, or as an outer vest with jeans or leggings.

Thin and Poor Quality

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

These vests have always been perfect for me, nice and warm, thick and cotton. They are certainly not the same quality now. They are very thin, feel more like polyester, not warm, very poor quality.

Vest top material is fine but soft warm and a nice length. I’d recommend it to anyone.

Slim and silky but warm. Does the job.

Bought for winter warmth. Nice vest and not bulky under tops. Would be even better if it had short sleeves.

This is all I ever wanted from a vest - lightweight and warm. It’s such a pity you don’t do it in colours other black.
