The utility model provides a new -type compound environmental protection natural leather that breathes freely, the upper surface on the 2nd natural leather layer have laid a plurality of and the mutually staggered second pit of each first pit, and a plurality of and third pit each first pit one -to -one are laid to the lower surface, and a plurality of and fourth pit each second pit one -to -one are laid to the upper surface on the 3rd natural leather layer. Each pit detachable allosterism becomes the gasbag, because the natural pore that each natural leather layer has utilizes each gasbag as the maincenter of switching on as the bleeder vent, switches on downside on a natural leather layer and the 3rd natural leather layer. And which side atress no matter, each gasbag all can carry out elastic deformation, carries out the respiratory movement, can further strengthen to go up downside ventilation effect, when mutually staggered each pit can guarantee that the downside is ventilative on a natural leather layer
