The present application provides a comfortable lightweight bullet-proof and stab-resistant suit and a preparation method thereof. A first aspect of the present application provides a comfortable lightweight bullet-proof and stab-resistant suit, including a sheath and a protection core sheet disposed in the sheath, and the protection core sheet includes a first protection layer, a second protection layer, a third protection layer and a buffer layer which are sequentially stacked together. The bullet-proof and stab-resistant suit provided in the present application has better response protection characteristics in the process of bullet penetration or knife tip stab, and the prepared aramid unidirectional cloth has low areal density, apparent flatness, no bubbles, and excellent softness, so that any bending within 180° can be realized.
