Castelli Go Cycling JacketA brilliantly versatile windproof and water-resistant jacket, the Castelli Go Cycling Jacket will keep you comfortable across a broad range of conditions and temperatures. The Go Cycling Jacket makes use of the same GORE-TEX INFINIUM™ WINDSTOPPER® three-layer stretch fabric as their iconic Alpha ROS 2 jacket. However, it forgoes the Alpha’s integrated insulating layer, allowing you to tailor your base layer weight and insulation levels, giving you comfort across a wide variety of temperatures. With the INFINIUM™ WINDSTOPPER® preventing cold winds from robbing body heat, you’ll soon feel, and hold onto, the warmth you generate through riding. It’s highly breathable too, so a sudden injection of pace or a stiff climb won’t result in you being soaked in sweat. Lastly, water-resistance also keeps off light rain and road spray.With weather protection taken care of, next comes the Castelli fit. The tailoring ensures a close, streamlined fit, but one with some space for layering and to be suitable for all shapes and sizes. A no-sew hem gives the jacket a smooth elegantly technical finish while hidden internal cuffs at the wrist boost comfort by eliminating drafts.Three rear pockets give plenty of space to load up for your longest of rides and a large reflective strip across the bottom ensures you’re visible when training finishes after dark.Similar in warmth to a Perfetto ROS Long Sleeve, the Go Cycling Jacket gets a slightly more relaxed fit and a more tailored look for those of you not in race mode. Stretchy, comfortable, breathable, windproof, water-resistant, elegant, and lightweight, this jacket has it all. Get out and Go.Features:Materials: 100% PolyesterFull soft-shell construction with GORE-TEX INFINIUM™ WINDSTOPPER ® 150 keeps cold wind out while offering exceptional breathabilityExcellent stretch with a neutral fit for extra comfortInternal stretch wrist closure for perfect glove interfaceZippered chest pocketYKK® Vislon® zipper with rubberized zipper pullNo-sew waist construction for clean, technical look3 rear pocketsLarge reflective strip across pockets for low-light visibilityWeight: 291g (M)Suggested temperature range: 4 to 14 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
