The Spitfire Tempest Protect Winter Jacket is a highly insulative winter training jack with strategically placed Pixel inserts. This jacket is made with our reknown Tempest Protect fabric. This 100% windproof and water repellent fabric provides superior wind and rain protection, even when you're training at a lower pace and intensity. When you're training outside during winter time, visibility and safety is a big issue. We've thought about that, too. Shoulder inserts are made of our Black Pixel, a highly reflective fabric that combines the windproof and water repellent characteristics of Tempest Protect with great visibility. The 3 back pockets are made of a waterproof PU coated fabric. For this year, we've implemented an extra lining on top of the pockets to provide extra protection. The sleeves feature a long and narrow cuff. This improves fit.
