When the weather outside isn't doing you any favors, stay motivated with smart layers that work as hard as you do. Smartwool's 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.
Warmer Merino/polyester blend ensures fabric moves moisture, dries quickly, and maintains its shape in high-sweat activites in colder weather
Minimal Merrow seam construction provides superior durability and is soft against skin
Gender-specific body-mapped mesh panels for additional breathability and moisture management
