The Spitfire Tempest Spring Jack is developed to meet the needs of racers looking for a warm, insulative and highly visible jack, without being over-insulated during medium to high intensity trainings. Instead of the warmer Tempest Protect fabric, Bioracer have used Tempest. This fabric is 75% windproof, which means that it gives just the right protection when you’re training hard during the winter months.
When you’re training outside during winter time, visibility and safety is a big issue. Bioracer have thought about that, too. They’ve implemented a Black Pixel insert in the torso front and on the shoulders. Black Pixel is a highly reflective fabric that combines the windproof and water repellent characteristics of Tempest with great visibility.
The 3 easily reachable back pockets are improved, too, and there’s an extra lining on top of the pockets to provide extra protection.
The sleeves feature a long and narrow cuff. This improves fit.
