Not cotton

I thought this product was made from supima cotton as I have bought same style previously. I should have checked the fabric details.

Lightweight & warm.

Yes, I recommend this

Bought a size bigger as a review had suggested they come small. Very happy with this size, not at all baggy & a lovely slinky feel against the skin. Nice & long so keeps the midriff & hips lovely & warm. Wish it came in white or flesh colour too - as I intend to wear them under pale coloured blouses in the spring.

Excellent and sexy!!

Yes, I recommend this

Excellent. I’ve worn these Heatgen thermal vests for a few year now, I love them. My daughter was cold and I said she should get some thermal vests, like mine. She said they’re not sexy!! Ordered her a double pack of your Heatgen vests. She loves them and loves the feeling of them on as well as being finally warm!!
