The front of the Agravic is Polartec Alpha, to provide warmth at an incredibly light, barely-there weight, while the outer is windproof and water-resistant Pertex Quantum. It packs down into itself, making it hard to believe that it could keep you warm, but it does. Not only that, but once you start to work hard it breathes exceptionally well. It does feel quite delicate, so it’s not one for bashing through thorns in, and the thin sleeves get cold when wet. The cut isn’t bike-specific but the back and arms are sufficiently long, and gripper on the rear hem keeps it in place. There are two zipped hand pockets, and the hood (which flaps around when riding) and hem are adjustable. It’s well-insulated and good for cold but dry rides. On damp days you’ll want to stick a waterproof over the top. Weight 151g Price $180
