Q36.5 Dottore Woolf Long Sleeve Jersey - UnisexUnusually for a thermal long sleeve, the Woolf is both lightweight and breathable, thanks to Q36. 5's tech merino fabric blend, which provides stellar thermoregulation and warming even when wet. Think descending after a challenging climb or chasing sunsets home in the golden light of fall moments where you need a little more from your jersey. And if the weather changes for the worse, Woolf's water repellant finish will keep light rain off your back.
