Engineered to be worn in temperatures ranging from 8-15°C (46-59°F), the garment’s Ristretto fabric technology keeps most of the wind out, yet still allows an optimal amount of airflow in to evaporate sweat, 12 times more effectively than the original Gabba jacket – hence its name (which translates to ‘twelve’ from Italian). Castelli Global Brand Manager Steve Smith comments: “There’s never been a jacket like the Do.Di.Ci.. We see it as the spiritual heir to the Gabba for the way many people use the Gabba. Fabric technology innovation partnershipsCastelli partnered with fabric innovators ITTTAI to develop Ristretto fabric technology, utilising their membrane and lamination expertise to create a new PFAS-free fabric which combines advanced stretch as well as unrivalled breathability. “As soon as they start generating excess heat and sweat, our Ristretto technology will evaporate moisture at unprecedented levels, to keep their core body warmth stable. at keeping riders dry on the inside and at the right temperature.
