A bit disappointed

No, I don't recommend this

Bought a medium weight vest but found there’s not much difference thickness wise between that and the maximum. Also I don’t like the crew neck, much prefer a scoop neck which doesn’t show under different necklines. The alternative lightweight vests are paper thin so a lot to think about!

Warm and Cozy

Yes, I recommend this

Again very cosy top. I bought my late friends daughter two for Christmas and the tights as well as she is an artist working outside. I bought her the same last year and she loves them. So do I.

Sooo comfy

Yes, I recommend this

Looks great under a lightweight jumper for early Spring when weather unpredictable. Lovely soft cream colour. Now have 3! Usually size 12, however always size up one size in thermals.

Poor quality

No, I don't recommend this

The material of this thermal top is poor quality, it snagged on the first wearing and bobbled. I went up a size for a good comfortable fit. Shan’t buy again very disappointed as usually can rely on M&S for quality

They last for ages

Really useful tops, and i wear them from the end of September through until Spring. Theyre really comfy, wash well, and dry quickly too.

Best fitting thermal top

Yes, I recommend this

I dislike tight clothes so bought this top a size larger but it still looked small. Once I put it on, it wasn't at all uncomfortable. The fabric is soft and warm and the neck seams don't irritate. I bought another one

Yes, I recommend this

Purchased the burgundy with 20% off which is a bargain, I’ve now purchased the cream. I sized up and am glad I did as a snug fit but length is good. Really lovely feel to the fabric and so comfy and warm. Ideal as a base layer but also smart to wear as the top layer if preferred. Definitely recommend.

Soft and comfortable

Yes, I recommend this

The top is comfortable and long enough to tuck in to keep the back warm. You can wear it with just a jumper on top to keep snug all day.

Poor quality item - very disappointing

No, I don't recommend this

I was so disappointed with this item of clothing. It looked great and the fabric was very soft and cosy. Sadly after only my first wear there were "friction" type marks on the back and front of the top. I had just worn it as a base layer under a fleece on a very chilly day. Surely this shouldn't happen so quickly, can only assume that the material is substandard. Very unusual for M&S. Slightly worried that I also bought this top in two other colours! Returned the faulty top for a full refund without any issues. Excellent customer services as always.

So versatile

Yes, I recommend this

Love these crew neck thermal tops. Have had scoop necked and high necked versions but these are so comfy under sweaters as well as fleeces, in the cold weather. I am a size 6 for M&S generally and buy these in size 8 for comfort. Have worn them practically daily this winter.

Perfect base layer

Yes, I recommend this

I have several of these now - so soft and cosy. As others have suggested, I buy the next size up as they are a snug fit. They wash well, no shrinkage.
