The Gabba Windstopper rain jersey is a textbook Castelli product innovation. The Gabba is phenomenal because it keeps out the elements while offering excellent breathability and super stretch for a perfect fit when riding. This version is light like a standard jersey but protects like a jacket. It's deceptively warm yet doesn't overheat in moderate conditions and if you get rained on you get the bonus of Gabba protection. With this, the latest version, you also get improved placement of zipped vents as well as breathable panels on the back of the sleeves. This is in addition to a refined fit, improved drainage in the pockets and improved construction of the waistband. Making a stellar product even better!
Exclusively engineered by Castelli, NanoFlex consists of Thermoflex fabric with millions of tiny silicone nanofilaments on the surface to create the most water-repellent finish ever. In wet conditions, water droplets simply bounce off the fabric without leaving a trace. The silicone nanofilaments also trap a layer of air between them for excellent insulation and prevent water from soaking through to the fabric underneath. In dry conditions, Nanoflex provides the same warmth and feel of regular thermoflex fabric. NanoFlex is notÂ completelyÂ waterproof but maintains full stretch, breathability and freedom of movement for weatherproof protection with un-compromised performance in all conditions.
