COSY THERMAL T SHIRT

Yes, I recommend this

I really like this thermal top. Superb for layering or wearing alone, dependent upon the outside temperature! It's a really good fit and feels good next to my skin.

Excellent quality. Watch the sizing.

Yes, I recommend this

Just written a review for the thicker tops where the sizing is definitely off. This top is excellent quality with a modern fabric. Having bought the thicker ones and ended up having 2 sizes up, I have settled for 1 size up on this one as the fabric is thinner and it’s ok.

Toasty, toasty, toasty!

Yes, I recommend this

Bought as a Xmas gift for my mum who is frugal with her central heating. I feel the cold (even with the heating on!) and I bought a couple of these last year for myself they are really toasty and very good quality! Wash beautifully!

comfortable basic base layer

No, I don't recommend this

This is a lighter weight thermal which is a good base layer for cooler days but not if needing good insulation

Great thermal top

Yes, I recommend this

So far I've been wearing this as a very cosy thermal vest under a jumper, but I think it may be substantial enough to wear as a top, as it's not too clingy. I love it and intend to buy another one. I've yet to find out how well it washes, but the reviews were encouraging.
