The Castelli Nano Flex bib short features a water-repellent stretch woven thermal fabric and Kiss Air seat pad. You will find these the perfect short for cool damp rides, wet races, early season sportives, gravel or cross adventures and numerous other situations.
In dry conditions, Nano Flex fabric is stretchy breathable and thanks to the brushed inner surface warm. But in damp conditions, the nanotechnology water-repellant surface keeps much of the moisture at bay. In heavier rain, some moisture will get through but the shorts never get waterlogged and retain their thermal qualities even when damp. They also dry quickly.
The Nano Flex bib shorts feature the Castelli Kiss Air seat pad. Its dual density padding with infinitely variable thickness combined with anatomical shaping ensures all-day comfort with cushioning just where you need it and with none of the bulk of less sophisticated pads.
A full mesh bib keeps the shorts in place without affecting breathability while the Giro3 leg grippers stop the legs from creeping up.
These are a utility piece for wet days so don't expect any colours, its black only. But a reflective Castelli screen print on both legs as well as rear-facing reflective tabs help you to be seen on dark roads.
