When the weather outside isn't giving you any favors, stay motivated with smart layers that work as hard as you do. Our PhD® Ultra Light fabric combines the temperature and moisture regulating properties of Merino with polyester for greater stretch and recovery and quicker dry time than Merino alone. Gender-specific mesh panels increase breathability.
