Yep, 60% wool, 40% polypro. As mentioned, I have two. They insulate well, dry quickly and hold no odor (I wear one daily in the winter, including my commute to and from work and fat biking on the weekend, and wash them maybe every three weeks). I also have 100% merino Smartwool that I wear. Can't tell a difference between the two, except that the SW is double the cost.
