Size-wise, I'd say this is a pretty average 22 (nothing wrong with that!) and is extremely comfortable against the skin with no scratchy labels or seams. Personally, I much prefer thermals with this type of high-neck and zip opening (as opposed to a round neck) as it provides different options in our unpredictable British climate! Easy wash & quick to dry. I've no idea how this would compare to an extremely expensive, super-hi-tech version: all I can say is, for the price, it's very good quality, very well made, and lovely & warm!
