Giro: STAY WARM WITHOUT OVERHEATING Keeping warm without getting too hot is a fine balance as you switch between high-output climbing and chilling descents. This jacket has strategically-placed insulation on the front panel and sleeves to keep you warm in key areas to keep your core warm and comfortable. The Polartec® Alpha® Insulation has openings to allow your heat to stay in when needed, or escape as things start to heat up. Paired with our wind-resistant outer layer that still allows ample breathability and an entire back panel that is un-insulated so your heat can escape easiest where you need it most, this is the piece to keep your cool when it gets cold.
