Very cosy

Originally posted on marksandspencer.com (UK)

I was recommended these as I am tall and was told they were a good length. They are great. On first examination seemed rather thin but kept me toasty underneath a sweater.

Comfortable, warm and cosy

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I've bought these before, and bought some extras because i now where them almost every day in the winter. They are so comfortable and cosy, and are easy to wear underneath layers such as jumpers and hoodies. Even the lightweight ones make a big difference, keeping me warmer at home, but not making me feel too hot and uncomfortable if i go out to a coffee shop. They wash really well and dry fast.

Disappointing product

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

These tops were a lot thinner than I expected and tended to roll up when I wore them which nullified any extra warmth they may have given. Particularly hopeless under a thin jumper which is when I mainly used them.

I've worn Heatgen tops from M&S for the last few years, they are SO soft, stretchy, snug and warm. I loved these colours and the two pack is a good price. I'm actually still wearing heatgen thermal tops I bought nearly 8 years ago, they are that good! Highlt recommend 👌

Light but warm

Light but warm. These are the lowest level of the thermal tops but still cost as a base layer

Good top for layering up without being bulky

Originally posted on marksandspencer.com (UK)

These are my ‘go to’ long sleeved top. This is a lighter weight thermal which I prefer to add an extra layer for warmth - so not bulky. I would highly recommend.

A bit disappointing

Originally posted on marksandspencer.com (UK)

The tops were very thin and not what I expected from a thermal garment. They were also very small fitting and clingy.

Very cosy

Originally posted on marksandspencer.com (UK)

Love the material, felt so cosy. Loved the length as it covered my bottom. Long sleeved top kept me warm. Liked the lower cut of neck as it didn't show underneath my tops etc Highly recommend.
