Simple warm vest

Yes, I recommend this

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

Great first layer

Yes, I recommend this

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.

Yes, I recommend this

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!

Yes, I recommend this

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!

Thin and Poor Quality

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.

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.
