Bought one in Dec 24 for me and it is excellent, comfortable, warm, and lovely smart turtle neck under jumpers. Tried to order for a friend as she liked the look of it so much but you have replaced with “mock” neck, which is not so high and looks cheap, unfinished and baggy. Had to send back. Please bring back the turtle neck!

Good quality. Good fit. Like the turtle neck which is a good fit, not baggy. Like the style, in fact it can be worn as a light top under cardigans/jackets. Intend to buy another. Worn but not yet washed.

Good quality thermal top. But is quite long for some 5’3’’ so I will have to shorten it!

A soft thin top that provides lots of warmth

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I'd wanted a thermal top with more coverage to wear under my uniform. It is soft, snug, and long enough to sit on the tops of my thighs. The weight of this top is warm enough without it being bulky. I am a big fan of the heatgen range - don't think I can survive the cold conditions at work without it!

Excellent buy for keeping warm.

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

This base layer has been an excellent purchase to wear when working outside in the garden. It is soft, the neck not too high or tight and allows for free movement. It is long, this is good for keeping your lower back warm but I am just over 5 ft and it comes down to mid thigh. It does make a lot of material to tuck in!

Cosy enough to wear by itself and fine enough to fit under another jumper during colder weather.

Love this top. Not only does it keep out the cold, but it looks great under a whole range of other items due to it being a roll neck top. Very comfortable.

This is a warm, comfortable, quality base layer, love the turtle neck, a really good length. It has washed well and keeps it shape. Would have loved it in another colour as well.
