I love these thermals. They're warm, work well used as a shirt or as a layer when it gets really cold. Kingsize's QC leaves something to be desired, though...I have purchased eight of these in the past two years and from that sample size:-one has a greatly oversized wrist cuff on the left sleeve, so it just hangs down to my fingertips-one has a an oversized collar, almost 2" larger in circumference than the others of the same shirt size-two have both of the above issues-one came to me with bad stitching on the hemThat's 5/8 items with manufacturing defects, and 3 of them were bought on clearance so I couldn't return or exchange them, and I had to seek repair by a local seamstress. This time I paid full price through amazon and one of the two has oversized cuff issue so I'll definitely be returning.
