Nice warm top

Yes, I recommend this

A warm top but just too fitted for me. I think I bought a bigger size to allow for this, but it was still too tight.

Excellent thermal vest in navy

Yes, I recommend this

Really excellent thermal vest, very warm. I like the fact that they do them in navy as personally don't like black. In case it's useful, I am usually a size 14/16 top at Marks but ended up buying these in size 20. I understand that they are usually an 'under' layer, but I don't like the feel of polyester against my skin and wear them at home over something else. If you do that, I'd suggest going up a couple of sizes.

These thermals are very effective-demonstrated by the fact they’re often out of stock-I’ve bought them for the whole family-very pleased with them

Thermal vests

Yes, I recommend this

Fantastic thermal vests cosy wash well and go straight back into shape. This revie is for the ordinary round/crew necks. I don’t recommend the raised necks as they aren’t stitched down and constantly move about and pop out over jumpers.

Snug thermal top

Brilliant thermal tops. I bought two. I bought the two star version as well. Had to go up a size from 18 to 20 but not over large fits me perfect normally a size 18. They have washed brill no shrinkage or pulling out of shape. Really recommend for this horrendous cold weather we have been having. Really good when out with the dog on my wintry walks.

Warm and cosy

Yes, I recommend this

I love these tops. Soft, command incredibly warm. Different weights in assorted colours. My only complaint is that I ordered two. Same style different colours. They were delivered separately on two consecutive days in plastic bags!! Why? Come on M&S you can organise yourselves better than that!
