Well, you don't have to choose between the two with the Smartwool Men's PhD Light Long-Sleeve Shirt. Made with a high performing blend of merino wool and polyester, the PhD Light shirt combines the temperature regulating, anti-odor prowess of merino wool with the moisture-wicking capabilities of polyester, making it a great shirt for any high-aerobic pursuit.
