Product Details LIGHT, WINDPROOF AND WITH TEMPERATURE REGULATION. Designed to provide outstanding support to cross country athletes down to the very last detail. Patented technologies on the chest, collar and cuff provide effective protection from low temperatures. At the same time, they allow a dynamic exchange of air and create a constant, pleasant climate for your skin. The X-BIONIC Cross Country SphereWind Light Jacket communicates perfectly with the X-BIONIC SystemGear Decision Layer beneath it. 3D-BionicSphere System on the back - Guarantees effective ventilation so moisture is quickly wicked and transported away. No sweat means insulating air pockets in the wavelike structure protect against cold. RodTypePaddings - Placed on the back, above and below the 3D-BionicSphere-System, they ensure effective ventilation. Due to their special design they also work under pressure. Their great elasticity guarantees that the temperature-regulating woven design fits on the body perfectly. MicroDiffuser on the collar - The ducts on the inside of collar allow hot, moist air to escape and support the body temperature inside the jacket. MicroDiffuser on the cuff - Precise ducts on the cuff create a highly comfortable band on the sleeve and let the moist, hot air escape. Pockets positioned slightly higher, with zip - The front pockets are also easily accessible when wearing a backpack and provide sufficient space for important items. The inside material is warm and soft, perfect to warm up cold hands. Reflective logo on the front and the back - For good visibility and improved safety at dawn, dusk and at night. Outer material: symbionic membrane - The unique, wind proof symbionic membrane is based on bionic research in connection with the skin breathing of amphibians. Symbionic is a closed membrane that has no pores that can become obstructed. Droplets of perspiration are distributed thoroughly along the interior side and drawn into the membrane, which has a structure that can process and whisk outwards a lot of moisture. That works with water vapour plus droplets of perspiration. Zip fasteners - Handy zips at the bottom of the trouser aid dressing. Inner pocket for mobile phone or MP3 player - A safe place with quick access inside the jacket.International Buyers – Please Note: Your order may be subject to customs charges and/or import fees if you are having an item delivered to a location outside of the UK.
