CASTELLI 4522509-030 MORTIROLO 6S JACKET Jacket Men's DARK GRAY/SILVER Size M

The perfect jacket for mild winters or for the cyclist who tends to overheat. This garment features our warmly insulated GORE-TEX INFINIUM WINDSTOPPER fabric on the front and sleeves, while the back has no membrane to let moisture out. It is a loose fit jacket that fits most body types. The Mortirolo Jacket has been designed to be a warm and comfortable jacket on cool days, capable of avoiding overheating and the accumulation of humidity inside the jacket. Choose this jacket for riding in cool but not freezing temperatures or for high-intensity rides or if you tend to sweat a lot. This jacket excels in a wide range of conditions, as long as it's not very cold or rainy. It's the combination of the right fabrics and the right construction that make it work so well. The upper chest and arms are where you get the coldest, so we use our three-layer GORE-TEX INFINIUM WINDSTOPPER X-Fast fabric with a luxurious fleece inside for added warmth. The underside of the front is in our mid-weight GORE-TEX INFINIUM WINDSTOPPER fabric with a lightly brushed inner surface. Both of these fabrics offer 100% wind protection, excellent spray protection and best-in-class breathability. The back is in our 100% polyester Warmer brushed fleece fabric with great breathability. It's not windproof, so it lets out a lot of moisture. You stay drier and consequently warmer and more comfortable. The jacket has a neutral fit. It's not overly race cut, so there's room to throw an extra layer underneath, but it certainly won't flap in the wind.
