The TracTech Evo 4 is a jean version of the one piece suit. Made from Cowhide leather, Samtex with stretch leather motion panels and fixed mesh lining, the jean has been cut with a less aggressive stance; as such, it is more comfortable to walk around in. The jacket can be easily attached to any pair of RST jeans such as the TracTech Evo 4 leather jean via the 360° connection zip – The TracTech Evo 4 is a great sports riding combination.
