A protective material structure comprising, in the order from the inside to the outside, an inner lining (10), a liner (20) and an outer layer (30); the liner (20) is disposed between the outer layer (30) and the inner lining (10) and can be wholly detached; the material of the inner lining (10) is chiffon with good air permeability; the liner (20) comprises, in the order from the inside to the outside, a first protective layer (210), a buffer layer (202) and a second protective layer (203). The outer layer (30) is made of polyester for waterproof insulation. The liner of the protective material structure is composed of a three-layer structure; the first protective layer and the second protective layer can quickly catch sharp weapons from the outside and reduce the impact speed, defense against cutting and piercing from low-speed sharp weapons; in addition, flexible materials is used, which is light and soft. The buffer layer can quickly dissipate the impact energy from the outside and reduce blunt injuries o
