Mediocre, not usual Marks quality.

No, I don't recommend this

I bought it for warmth. It’s not particularly warm and the vests are stretchy but ride up unless tucked in. Disappointed.

Perfect lightweight thermal

Yes, I recommend this

Perfect fit and long enough to tuck in. Keep me warm without being overly hot which I tend to be when wearing the long sleeved thermals. Pack small which is great for a weekend trip to Poland.

Just what I needed

So soft and comfortable. I am currently unable to bear most clothes over the (healing) wound site of a heart pacemaker insertion site but these are just right. And they're light but cosy.

Essential tops for winter

Yes, I recommend this

Love hese short sleeved tops.. Thin but warm so go under anything. Have black and cream ones. Do purchase size 12 instead of 10 to give a bit more room.

Great item

Yes, I recommend this

These are really warm. They fit like a second skin but are so stretchy and soft they aren't tight or restrictive at all. I also have long sleeved version and will certainly buy more.
