The De Marchi Contour Insulator Jacket builds upon the efficient construct and sophisticated, three-dimensional fit of the Contour long-sleeve jersey, but instead using the heavier-weight Thermolite Roubaix fabric. This allows you the freedom to wear it atop a jersey or short-sleeve base layer for cool rides, or together with a wind vest on those extra-cold days -- the latter of which wouldn't be possible without the jacket's signature anatomical fit. Adding to the unique ergonomics of this jacket, are the elongated, asymmetric cuffs which ensure complete coverage over your wrists no matter how deep in the drops you might find yourself. This Thermolite Roubaix fabric is the next evolution in the vein of the celebrated Italian fabric, Super Roubaix. The benefits of this fabric in the jacket are clear, as the core of this toasty fleece-backed fabric is made from hollow Thermolite fibers which reduce the fabric's overall weight while enhancing its thermal capacity. The outward-facing sides of the fabric is also treated with a protective Teflon application which helps better shield you from wet spray or mud stains. The De Marchi Contour Insulated Jacket comes in Black, and in six sizes: Small through XXX-Large. Three generous back pockets enable you to carry whatever you might need to stay warm and nourished for your pre-season training sessions. Low-profile reflective flags on the front and back of the jacket ensure an added level of visibility should you be out after dusk.
