Made from a warm twill-woven blend of cotton and wool, our regular fit Tech Prep™ Wool Shirt is treated with a Tech Prep™ finish, engineered to maintain your temperature at a perfect 37.5 degrees. This process was originally developed for space travel, and when added to our shirts it combines function with extreme softness.
