Castelli Tutto Nano BibknickerSpring and autumn see cool temperatures and frequent rain showers but you don't necessarily need or want full leg coverage. This is where the Castelli Tutto Nano Bibknickers come in, protecting from cool temperatures and sudden showers but leaving your calves free to enjoy fresh cooling air. The Wonders of NanotechnologyPivotal to the all-round protection offered by the Tutto Nano Bibknickers is their use of warm and water-resistant Nano Flex 3G fabric. This amazing material makes use of a nanotechnology microfilament mechanical water repellent finish combined with a short-chain chemical DWR finish to ensure water is prevented from soaking in for longer, keeping you more comfortable when wet weather strikes. Its excellent thermal performance will also lock in heat while a reduction in seams adds to their ability to resist water ingress. While the lower body and legs are protected, the mesh bibs to the top prevent a build-up of perspiration, regulating your temperature so you don't overheat and feel uncomfortable. Kiss Air2 Seat PadThe Tutto Nano features the ever-reliable Kiss Air2 seat pad, incorporating many of the comfort-focused features of Castelli's top-of-the-range chamois. In any cycling garment, comfort is paramount and the anatomical shape of the Kiss Air2 pad ensures maximum comfort, no matter how long you're on the bike. Dual-density foam is used to provide variable thickness - padding where it's needed and less where it isn't, to maximise your freedom of movement on and off the bike. Finally, a brushed microfibre top layer, with superior softness and an anti-bacterial treatment eliminates chafing and saddle sores.Whatever the weather has in store for you the Tutto Nano Bibknicker is Castelli's answer to that cool-weather conundrum of what to wear for a day of riding that sees almost every season make an appearance.Features:Materials: 85% Polyamide, 15% ElastaneNew Nano Flex 3G fabric is exceptionally warm and soft yet with even better rain protectionReduced seaming for improved comfort and fitMesh bib straps don't hold moistureKISS Air2 seat pad for long-distance comfortReflective leg ending with ankle zipEmbossed logos for durabilitySuggested Temperature Range: 4 to 16 Degrees CBuy Castelli  Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
