The LUXE Air Vest combines a protective front shell with high-loft active insulation and a fleece back panel, folding two layers of protection into something that wears like a single jersey. That zoning lets the vest block wind up front while venting heat out the back, so warmth never comes at the cost of breathability. What Our Gearhead® Experts Are Saying:"I started a cold morning ride fully zipped and never had to stop to shed a layer once the effort picked up. The back stayed cool while my chest stayed protected the whole way through."
