Castelli Elemento 2 7x(Air) Cycling Jacket Men's Size M Color Black

7xAIR Catelli used the best winter membrane fabrics on the market but still find ourselves wanting more breathability. That's why they invented 7xAIR. It starts with a fully wind and waterproof external layer and then quilt it to a fleece inner layer using the trapunto technique. This results in an extremely stretchy wind resistant fabric, but the stitch holes give just the right amount of air permeability and allow for a continuous exchange of air on the inside of the garment, which carries away moisture much better than fully sealed fabrics. This actually makes it warmer because there's less unwanted air flowing on the inside of the garment. There must be a downside, right You definitely wouldn't take this out on a rainy day, since rain will come through the quilting stitching, though the fabric is DWR treated and will shed light spray. But it's ideal for your five hour base fitness rides as well as your one hour lunchtime world championship rides. Breathability is good. 7xAIR fabric technology meets Alpha construction to make your ultimate winter jacket Castelli Exclusive 7xAIR Quilted Fabric With WindShear inserts Fleece Lined For warmth with separate fleece layer on front Articulated Fleece Collar Gently wraps around the neck in every cycling position Raw Edge Wrist cuffs and waist lie flat and seal out the cold A new standard in balancing light weight, stretch, breathability and warmth 3 external rear pockets plus zippered chest key pocket Close to body aero fit Reflective tabs Weight : 545g Size M Color Black
