The Velocio Luxe Air Jacket layers body-mapped 80g insulation under a lightweight, 100% recycled polyester shell built for rides between 25 and 55 degrees. We map the insulation to the body so it holds warmth through the chest and arms while a fleece back and underarm panel vent heat once the effort picks up. A 2-way front zipper lets us dump heat fast without stopping to strip a layer. What Our Gearhead(R) Experts Are Saying:"I've climbed hard enough in this to need the zipper open by the top, and the fleece panel under my arms kept me from overheating before I even reached for it. It's the first cold-weather jacket I don't end up carrying home tied around my waist."
