WHO SAYS BIBSHORTS AREN’T WARM ENOUGH FOR CHILLY AND WET MORNING RIDES? Our Nano Flex water-repellent fabric is one of those fabrics that seems miraculous. On a dry day it’s as warm and breathable as our normal Thermoflex fabric, but when it rains the water just runs off, thanks to the five-phase nanotechnology treatment. While it’s not 100% waterproof, it’s the best solution we’ve ever tried for staying comfortable in any conditions. On a wet day, pair the Claudio bibshorts with a set of our fleecy and water-repellent Nano Flex knee or leg warmers and you’ll feel the same warmth as with a pair of tights.
