We took our experience using waterproof / breathable laminated fabrics, and crafted a light weight seam sealed jacket with large direct core vents that can be used when it’s warm or when it gets cold and wet. Unlike traditional venting systems that send air to the outside of a liner, the direct core vents send air directly to the wearers body and is therefore more effective. when the weather changes from good to bad, all you have to do is zip a few waterproof vents shut, to keep riding. No more zipping in a separate waterproof liner. An EverHeat® thermal liner is included for those chilly days or when the temperature drops. the jacket has Exo-Tec® CE certified armor on the elbows and shoulders, and a pocket with PE foam as a back pad that can be upgraded. go ahead, ride when you want, in whatever weather you want.
