We present an analysis of the characteristics of the Interplanetary Coronal Mass Ejections (ICMEs) sheaths and their evolution as a function of distance in the inner Heliosphere. In detail, we aim to unravel different characteristics of these structures occurring over the inner Heliosphere such as the size variation and the density fluctuation evolution with the heliocentric distance.
