The Castelli Nano Flex Bibtight is the perfect legwear choice for cool damp days in the saddle. The nano-fabric is warm and breathable against the skin while shedding light rain and road spray.

In dry conditions, Nano Flex acts just like most other thermal fabrics, its 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 these bibtights never get waterlogged and will retain their thermal qualities even when damp. They also dry quickly.

These Nano Flex bibtights also feature the superb 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 these tights in place without affecting breathability while the Giro3 ankle grippers seal the tight over your shoe-covers - we recommend wearing the tight over the shoe-cover so any spray is diverted harmlessly away and not straight into your shoes.

These bibtights 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 in addition to the reflective trim on the YKK ankle zippers ensure your visibility.

Perfect for cool and damp days if you’re going to do serious rain riding, you should look to our Nano Flex Pro 2  Bibtight or even the Tempesta Pant, but for lighter rain, warmer temps or wet roads these will be ideal.
