Great value and lovely and soft

No, I don't recommend this

Good fit and very soft to wear. Does not look like a thermal T shirt so can wear as a T shirt as well

Incredibly comfortable

Yes, I recommend this

I'd had one of these long sleeve thermal tops for a few years and always found it so warm and comfortable to wear, so much better than my other thermals. So decided to get a couple more. Incredibly comfortable, you don't know you're wearing one. And they seem to wash and wash without any deterioration. Highly recommend.

Have bought dozens of these in all the various colours over the years. There have been occasions when the fabric has not been so good. But, this is good. Nice layering to keep warm…

Darker Green Version

Yes, I recommend this

Like these tops as longer in body than those sold for females and not so clingy, great for an extra layer for casual wear. I am tall so can get away with the longer body and longer arms. I have these in denim and last years dark red so thought I would try the green. It is not a vibrant green and is darker/duller in tone than I expected. These are not very thick and in themselves I would not say are very warm, but good for layering.

Light thermal, with the emphasis on 'light'

Yes, I recommend this

These are good. You get two in a pack, so they are not terribly expensive, but they are very lightweight and stretchy. They have less cotton in them than the medium weight thermals - these are 29% cotton vs. 50% cotton in the medium weight ones - and they feel a bit plasticky and synthetic in comparison.

Mens but good for ladies too !

Yes, I recommend this

Nice thin but warm tops, especially like the long sleeves and crew neck. Although they are mens I wear them as they are nice and long and comfy.
