The Castelli Estremo WS Skully is made for cold weather conditions. The Estremo WS Skully is fitted with the Windstopper X-Fast that ensures you are protected against the wind. The inside features Warmer what feels soft and warm. The beanie protects the ears so these stay warm during your bike ride.
Warmer: This fabric does exactly what it’s name suggests, it keeps you warm during exercise. The fleece lining keeps you warm, while the 100% polyester fibers drain sweat real fast. This material is ideal for the intermediate temperatures during spring and autumn, where thermal insulation and moisture transport are both important.
Windstopper X-Fast: The fabric offers full windproof protection, but remains very breathable. The inside of the fabric is brushed and provides excellent insulation. The brushed fabric also prevents moisture buildup behind the windproof layer, but transports the moisture to the outside. The outside is covered with a water-repellent finish.
