The Alpine Thermal has been designed for cool/cold weather rides and/or commuting in predominantly dry conditions. Alone it performs well in temperatures ranging between 40-65°F, with various vest and base layer combinations you can easily stay toasty down into the low 30's.
The Alpine Thermal RT Jersey is the latest to really impress. The fit is slim and spot on and the winter fabric keeps you very comfortable across a broad range of temperatures."
With a soft fleece lining, the Alpine Thermal Jersey is perfect for winter, serving us well even when temperatures dropped to freezing – we only had to resort to a rain cape if things got wet. Ultimately, this worked superbly for every dry ride, which meant no extra clothing. A full winter-ready bit of kit."
