Recently a new model for inflation with non Abelian gauge fields (Gauge-flation), was proposed. The isotropy of space-time is recovered by suitable combination of gauge configurations. In this model, a scalar field, is constructed by gauge field and the scale factor, which produces inflation period. In this work, exact (non-perturbative) solutions for the scalar field are presented. It is shown that such Cosmic-Gauge solitons (CGS) evolve through the inflationary, dust and radiation periods. We explicitly present Hubble parameter and CGS as functions of time and it is also demonstrated that they are damped oscillator. Moreover, reheating with CGS is discussed.
