Very Very long

No, I don't recommend this

Lovely quality, soft fabric but when measuring against standard t-shirts this is a good 9 inches longer. Just because it's thermal doesn't mean it has to be so long. It's also expensive and with only 3 colours not versatile.

Suitable for the ladies too!

Yes, I recommend this

I purchased two small thermal short sleeved men’s tops. I couldn’t find anything in the ladies section which had merino wool (there may have been, but I didn’t see any at the time). They are nice and long so your lower back is kept warm and they are very comfortable to wear. They are machine washable and dry quite quickly.

Yes, I recommend this

This is the warmest thermal vest in the store. My 85-year-old Husband really feels so cold and I have bought thermal vests in the past and they have been good but this one is absolutely super! He stopped moaning about the cold and he’s very very happy and warm. Well worth buying.!

Great thermal T-shirt

Yes, I recommend this

Soft and warming and long enough to tuck in, they can even be tumble dried. I cannot think of any negatives with them.
