The Castelli Sorpasso Rain or Shine Bib-knicker will keep you warm and dry on cooler days without restricting movement as you ride fast. Whether it’s dry or drizzling, water drops will roll off and sweat will evaporate. The warm and water-repellent Nano Flex 3G fabric is stretchy, breathable and it fits perfectly. Extra warmth and more wind protection are added on the hips and thighs with the Nano Flex Xtra Dry. The Nano Flex fabrics move with you as you accelerate out of the saddle, ride up a mountain road, or cruise along the coast. No material will crease nor will you feel excessive tightness. The fabric is treated with the third generation of nanotechnology that adds a high level of water repellency without interfering with breathability, stretch and warmth. Breathability is another feature that creates a performance level bib-tight that will keep you dry as a ride or race gets faster. Sweat will evaporate in an instant through the air that circulates through porous fabrics. The lie-flat elastic bib straps are comfortable under the multiple layers you may need to stay warm and dry in light rain on a fall or spring ride. As you are riding on low lit days, reflective inserts at the back increase visibility. Castelli’s Progetto X² Air seamless seat pad is Castelli’s best long-distance chamois pad. The fabric against the skin is soft and malleable and air circulates through the multilayers keeping you fresh and dry. Cushioning is provided by just the right amount of perforated padding with varying densities, so you are protected without feeling like you’re riding on unnecessary bulk. If you need wind and rain protection in colder weather try the Castelli Sorpasso RoS Bib-tight.
