Castelli Nano Flex Pro Race Bib ShortsThe Castelli Nano Flex Pro Race Bib Shorts are an evolution of the highly-regarded Omloop all-weather cycling shorts. They're now made from Nano Flex 3G, giving a boost to all-weather performance - be it wet, cold, dry or anything in-between the Nano Flex Pro provides the protection you need fr comfortable cycling. Just like their predecessor, the original Omloop thermal shorts, the Nano Flex Pro Race Bib Shorts feature the same extended leg length, the extra 10cm adding warmth across over the knees. You'll also enjoy the luxurious warmth of the Nano Flex fabric. It's as warm as Castelli's Thermoflex fabric, making it superb in cold dry weather. But with its nanotechnology treatment, you'll also get extra protection when rain clouds roll through and burst. For early season races and training where the weather can turn quickly from good to bad and back again, there’s nothing better.The shorts are tailored to fit beautifully but they use fewer seams in their construction. Not only does this reduce any chance of chafing but also ensures fewer areas for water to seep inside. Then there’s the superb Progetto X2 Air seamless seat pad inside. Utilising ventilating perforations, it keeps you more comfortable on endurance road rides. The design allows air and moisture to flow directly to the surface fabric for quick evaporation maintaining dryness. The seat pad is constructed with three-layer components, each dedicated to a specific purpose to create the most comfortable seat pad available.First created by Pro cyclists for the changeable conditions of Spring Classics races, the Nano Flex Pro Race Bib Shorts ensure you to enjoy extra weather protection when it comes to your own springtime training and racing.

Castelli Pro Thermal Mid Long Sleeve JerseyA bit lighter, a bit stretchier and a bit closer to the body than a regular thermal cycling top, the Castelli Pro Thermal Mid Long Sleeve Jersey is just right for cool conditions and high-intensity training. Come the transitional seasons of the year and while temperatures aren't freezing, the lightweight warmth of the Pro Thermal Mid Long Sleeve Jersey offers just enough warmth to keep off a chill. The secret is in the use of mid-weight Warmer X-Stretch brushed fabric. The fleece inner provides excellent insulation against cool weather but it's a touch lighter than a regular thermal material, ensuring better breathability and heat regulation. Not only warm and breathable, the X-Stretch, as the name suggests, has an extra amount of stretch, giving the jersey a snug fit. This combines with a race fit to deliver streamlined performance tailored for fast riding. The functional focus of the jersey continues into the details. A smooth YKK® Vislon® zipper can be used with one hand, making controlling ventilation simple. The drop-pocket construction allows you to load up and yet the jersey remains in a secure and stable position. There’s also a reflective stripe on the centre pocket, enhancing visibility after dark.Features:Materials: 80% Polyester, 20% ElastaneMid-weight Warmer X-Stretch brushed fabricIdeal for cool conditions, with or without a vestRace cut with highly elastic fabric provides close-to-body fit without feeling tightDrop-pocket construction for better fit around waist and better pocket positionEasy-sliding YKK® Vislon® zipperEmbossed line across chestReflective vertical stripe on centre pocketWeight: 228gSuggested Temperature range: 14 to 19 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
