Since the HH Dry Revolution LS Base Layer breaths so well you can keep dry while climbing. As a result you can throw a light jacket on for the descent since you’re not soaked. I throw the Helly Hansen H2 Flow Jacket on since it is light and easy to pack. On this 30 minute long downhill back to the trailhead I stayed toasty, and it was 10°F out!
This is a great base layer from the folks at Helly Hansen. It is soft, comfortable, wicks well and dries fast. You should definitely add one to your cool weather riding gear.
