Choosing the Right Castelli Jacket
Castelli jackets fall into clear categories based on weather and riding style.
Perfetto
Windproof, water resistant and highly breathable. A versatile choice for most UK conditions. | Shop Perfetto
Gabba
Short sleeve version of the Perfetto. Designed for racing and fast training with arm warmers.
Alpha
Warm, structured insulation with excellent ventilation. Best for deep winter and long rides.
Idro
Fully waterproof Gore Tex shell. Lightweight and packable for heavy rain.
Emergency Rain

Fit and Sizing
Castelli jackets use a performance fit. They sit close to the body to reduce drag and improve moisture management. If you prefer a relaxed fit or plan to layer heavily, consider sizing up. Women’s specific cuts are available for a better fit across the shoulders, chest and waist.
UK Weather Performance
Castelli jackets are well suited to the UK’s mix of cold, wet and windy conditions. Gore Tex Infinium handles most winter rides, while Nano Flex fabrics cope with damp roads and light showers. For persistent rain, a full Gore Tex shell like the Idro offers dependable waterproofing without excess weight.
Care and Longevity
Wash on a gentle cycle with mild detergent. Avoid fabric softeners. Close zips and turn the jacket inside out. Reproof water resistant fabrics when water stops beading on the surface. Hang dry to maintain shape and performance.
