I have two main complaints about this product.  One is that the size was much larger than the chart indicates.  The large size that I ordered is at least as big as extra large sizes that I've had in the past.  My other complaint is that these were made in China.  It was hard to see that information, since it wasn't on the web site, and it's almost hidden in a nearly-microscopic tag.  I guess that they wanted to conceal that fact.  Since it was made in China, the overall quality is suspect, but I won't know until I wear them and wash them for several months.  Other than that, they seem to be comfortable.  The material is a bit heavy for Summer wear, but if you keep the house at a comfortable temperature, around 70 degrees, they should be OK.
