Ok

No, I don't recommend this

The last ones I bought had a warmer lining. These are just cotton camis. A tiny bit short, I think.

Not Well Fitted and Quite Thin Fabric

Originally posted on marksandspencer.ie

I've bought several strappy vests from M&S over the years. They are usually well fitted to the body, although maybe sometimes too short. These vests are actually quite loose on the body, not well-fitted at all, and the bottoms of them are really quite floppy. I also can't figure out why they're called "Heatgen" because they're rather thin. Worried they're going to loose what shape they have very quickly.

Soft & comfy

Yes, I recommend this

I only buy undergarments from M&S due to sensitivity of my skin, and M&S always delivers on excellent quality with softness and comfort. Love these strappy vests!

Disappointing

Much thinner than expected, don't know if it will actually work as thermal. Good that it has the adjustable straps

I originally purchased these thermal cami last year and they were so good I purchased more this year. They are nice and long and give warmth for this time of year. I would highly recommend them.
