The Santini Adapt Multi is a revolutionary piece of winter kit designed to eliminate the "boil-in-the-bag" feeling of traditional rain shells. Engineered to fit and feel like a high-performance long-sleeve jersey, it provides the full-scale weather protection of a dedicated waterproof jacket. It is built for high-intensity training in cold, wet, and unpredictable conditions, where maintaining a stable core temperature is critical.
The secret to its performance lies in the Polartec® Power Shield™ fabric. This cutting-edge material features a bio-based membrane made from 48% plant-based materials and is entirely free of PFAS chemicals. With a formidable 20,000mm water column, it is effectively waterproof for all but the most extreme deluges, while remaining exceptionally breathable to move moisture away from your body during hard efforts on the climbs.
Polartec® Power Shield™ Membrane: A next-generation fabric that offers 20,000mm waterproofing and high breathability. It’s windproof, stretchy, and soft against the skin.
Fully Thermosealed: Every internal seam is taped to prevent water ingress, ensuring you stay dry even during prolonged exposure to rain.
Double-Slider Front Zip: Features a waterproof "two-way" zipper that allows you to unzip from the bottom for extra ventilation or to access jersey pockets without fully opening the jacket to the cold.
Thermo-Balanced Range: Optimized for temperatures between 0°C and +10°C. It provides significant warmth for its weight, though it layers perfectly over a base layer for colder mornings.
Enhanced High-Vis Details: Includes a prominent reflective shoulder band with the Santini logo and reflective details on the rear tail for maximum safety in low-light winter conditions.
Additional Waterproof Storage: Beyond standard rear pockets, it features a dedicated waterproof zippered rear pocket to keep your phone and electronics completely isolated from the rain.

The High-Intensity Rider: If you find yourself sweating through traditional rain jackets, the exceptional breathability of the Power Shield membrane will keep you much drier from the inside out.
The Aero Enthusiast: If you hate the "flapping" sound of loose rain shells, the slim, jersey-like fit of the Adapt Multi stays quiet and aerodynamic at speed.
Eco-Conscious Cyclists: One of the few high-performance jackets on the market utilizing a plant-based membrane and PFAS-free DWR treatments.
Casual/Relaxed Fits: This is a pro-cut slim garment. If you prefer a loose, "club fit" jacket for wearing over bulky street clothes, you may need to size up significantly or choose a more relaxed model.
Extreme Deep Winter (-5°C and below): While highly protective, this jacket has a minimalist lining. For sub-zero riding, it must be paired with a heavy thermal base layer or a dedicated insulated winter coat.
To maintain the 20,000mm waterproof performance, never wash this jacket with standard fabric softeners, as they can clog the pores of the Polartec membrane and ruin its breathability. Use a liquid tech-wash and wash at 30°C. A unique feature of the Adapt Multi is the internal label detailing the legendary climbs surrounding Santini’s home in Bergamo—a small nod to Italian cycling heritage to keep you inspired when the weather turns grim!
