Castelli Nano Mid Wind JerseyCreated to keep you comfortable when you’re training at speed in cool conditions, the Castelli Nano Mid Wind Jersey is close-fitting, windproof and warm. In the past, you may have reached for a jacket, but now you can reach for a jersey in cooler weather. The aim of the Nano Mid Wind Jersey is to give you jacket-like weather protection but with the fit and feel of a thermal cycling jersey. And to achieve this aim Castelli turns to their Warmer X-Stretch brushed fabric. This ensures you’re insulated from the cold but also, when you’re putting in higher intensity efforts, you’re not left drenched in sweat. While created for mostly dry conditions, a nanotechnology water-repellent finish will shrug off light rain and road spray. Protection from the elements is also boosted via the use of GORE-TEX INFINIUM™ 203 over the chest and shoulders. This material, usually found on their Gabba jackets, is both windproof and highly water-resistant, complementing the insulating properties of the Warmer X-Stretch fabric perfectly. The result is a jersey that is protective and yet remarkably light and flexible. With three rear pockets, you’ve got space to stash a rain jacket if you do happen to be caught in prolonged periods of rain. And with a reflective band to the back, you’ll also be easier to spot in low light.Features:Materials: 85% Polyester, 15% ElastaneMid-weight Warmer X-Stretch brushed fabricOverlays on chest and shoulders in GORE-TEX INFINIUM™ 203 Stretch fabricNanotechnology water-repellent treatment in case of light rain or wet roadsEasy-sliding full-length YKK® Vislon® zipper adjustmentSilicone gripper elastic3 rear pockets with a reflective band for visibilitySuggested temperature range: 9 to 16 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World’s Largest Online Bike Store.
