In dry weather, Castelli's Nano Flex fabric is stretchy, breathable and warm, thanks to its fleece-like inner surface. When it rains, the nanotechnology-enhanced water-repellent surface keeps most of the moisture on the outside. Since there's no membrane to block breathability, if it rains more or you go on a longer outing, some of that moisture can pass through the garment. But truth be told, these are ideal conditions for these Nano Flex 2 bib tights because they never feel like they're waterlogged, instead offering the feeling of almost completely dry legs, and best of all, they still keep you warm. If you feel like doing long workouts in the rain, you need the Nano Flex Pro 2 Bibtight or even the Tempesta Pant. But for light rain, milder weather or wet roads, the Nano Flex 2 Bibtight are ideal.
