More than common and generic ‘outdoor’ fleece jackets, these are both tailored and engineered for riding. Each Aerostich fleece jacket is made right alongside the Roadcrafter's and Darien's, and is designed to work perfectly within all of your riding gear. It's a warm, draft-blocking, comfortable, lightweight layer of added insulation perfect for your three and four season rides. They wear wonderfully off-the-bike, too. These jackets last about forever and have a bunch details that make a difference you will feel: We start using genuine advanced-technology Malden Polarfleece (…there are many kinds of copies and inferior fleeces) and YKK zippers. Sewing and design details are also notable: each collar is tapered for more comfort with a helmet strap and the sleeve diameter is trimmed down for less bulk under riding gear. Sleeves are more forward rotated, too. And the long underarm ventilation zippers match Roadcrafter suits. Durable Lycra/nylon bindings at the hem and sleeves are comfortable and stop drafts without absorbing water. The torso is a bit shorter in front and longer in back for a better fit, and the sleeves are usefully a bit longer than you’ll find in typical fleece jackets, too. Zippered inside and outside chest pockets secure valuables like cell phones and wallets, and zippered side pockets are placed slightly forward for easier access. A quick-draw inner chest pocket is ideal for sunglasses or a bandanna. This breathable, high-warmth, low-bulk jacket that will become your favorite the first time you put it on It’s the best riders' lightweight wind-blocking fleece jacket in the world, and one of the best for general wear, too.
