I chose this to wear under jeans when riding my motorcycle and am very glad I did. I looked at underarmour but felt it was to pricey at $50. The Duofold was perfect. I went from 65 degrees up to areas where there was snow on the side of the road then back down to 75 degrees and never was cold or hot. They were very comfortable and never bunched up. I would recommend. By the way I ordered my waist size 34 and they were a perfect fit. I'm 6'2 and the legs were plenty long enough.
